National Standard Publicity Conference for Rare Earth Lamp Phosphors and Rare Earth Luminescent Materials and Market Report Meeting Held in Zhuhai

On April 20, the National Standard Publicity Conference for Rare Earth Lamp Phosphors and the Rare Earth Luminescent Materials and Market Report Meeting were held in Zhuhai City. The conference was hosted by the National Technical Committee for Rare Earth Standardization and the National Rare Earth Phosphor and Lamp Cooperation Network, and co-organized by Guangdong Zhuhai Omec Instrument Co., Ltd.

Wu Hong, Director of the National Rare Earth Phosphor and Lamp Cooperation Network, emphasized in his speech the need to improve the quality of rare earth phosphors for lamps, so that phosphors can play a greater role. The price increase of rare earth phosphors and this revision of the standard should be regarded as new opportunities and challenges for the development of the fluorescent lamp industry. Zhu Yuhua, Chairman of the National Technical Committee for Rare Earth Standardization, delivered a speech discussing the characteristics of the revised standard and pointing out that the standard system should be further improved.

The report meeting was convened against the backdrop of the country's recent increase in rare earth resource taxes by more than 10 times and the implementation of the National Standard for Rare Earth Trichromatic Phosphors for Lamps starting from May 1 of this year. It is of great significance for the healthy development of the rare earth phosphor for lamps industry.

Huang Ruitian, Sales Manager of Jiangmen Keheng Industrial Co., Ltd., as the lead drafter of the standard revision, delivered a report on "Standards for Rare Earth Phosphor Powders Used in Lamps and Their Test Methods, and Reference Materials,

Wei Lan, Senior Engineer and Deputy Chief Engineer of Xiamen Tongshida New Materials Co., Ltd., delivered a report on the standards for yellow rare earth phosphors used in white LED lamps, their test methods, and reference materials, highlighting the scientific and rational aspects of the technical standards and test methods.

Xia Wei, Professor-level Senior Engineer and Deputy Chief Engineer of Dalian Luming Luminous Technology Co., Ltd., delivered a report on the standards for rare earth long-afterglow phosphors, their test methods, and reference materials.

Li Qian, Deputy Director of the Research Institute of Hangzhou Yuanfang Optoelectronic Information Co., Ltd., delivered a report on the standard test methods and equipment for the optical and colorimetric properties of phosphors, providing explanations on the standardization of test techniques for three types of rare earth luminescent materials and their secondary characteristics.

Professor Tang Yinxuan, General Manager of Hangzhou Daming Fluorescent Materials Co., Ltd., delivered a report on the market demand analysis and outlook for China's rare earth fluorescent materials in 2011.

Chen Yousan, Senior Engineer and Director of the Technical Center of Xiamen Tongshida New Materials Co., Ltd., delivered a report on the influence of the alumina (Al2O3) synthesis process on the structure and performance of BAM. The report described the relationship between alumina matrix materials and the conversion efficiency of synthesized BAM bimodal blue powder.

Dr. Zhang Fugen, General Manager of Guangdong Zhuhai Omec Instrument Co., Ltd., delivered a report on particle size testing technology and its application in the phosphor industry. Regarding how to obtain the optimal particle size distribution for coating, several different testing methods were discussed, clarifying the application of different testing methods for phosphor powders of varying particle size ranges, as well as their proprietary technology and equipment with independent intellectual property rights.

Liu Ronghui, Senior Engineer and Deputy Director of the Rare Earth Luminescence Division of the National Engineering Research Center for Rare Earth Materials and Grirem Advanced Materials Co., Ltd., delivered a report on white LED phosphor technology and its current application status and trends. The report systematically expounded on the application status and development prospects of YIG phosphors and oxynitrides for white LEDs.

Zhao Kun, Senior Engineer and Director of the Luminescent Materials R&D Center of Sichuan New Light Source Co., Ltd., delivered a report on the application of novel phosphors in white LED packaging for lighting. The report introduced a new AC-driven phosphor technology that addresses LED flicker issues.

Tian Yuwei, Senior Engineer and Chief Engineer of Jiangsu Zeming Fluorescent Materials Co., Ltd., delivered a report on the development of "high-brightness, long-afterglow" red phosphors. The report described the company's latest scientific research achievements in this field, with the brightness and afterglow time of this phosphor reaching new levels.

Wu Hong, Director of the National Rare Earth Phosphor and Lamp Collaboration Network, delivered a report titled "Development Opportunities and Challenges of Rare Earth Luminescent Materials and New Energy-Saving Light Sources." He reviewed the development history and achievements of rare earth phosphors for lamps, and pointed out that under the situation of simultaneous increases in rare earth taxes and rare earth product prices, phosphor enterprises must further improve cost performance, while putting forward targeted suggestions for future development.

These reports are rich in content and basically reflect the achievements in theoretical research and technological progress of the phosphor industry in recent years, especially the reports concerning standards, which indicate that phosphor products have entered a stage of standardized and normalized development from an extensive one.

The delegates also visited Zhuhai Omec Instrument Co., Ltd. and were deeply impressed by the particle size testing technology and equipment developed by the company. Over one hundred representatives from rare earth phosphor and energy-saving lamp enterprises, together with nearly one hundred relevant experts, attended the report meeting.
