This paper collects the patent data of rare earth luminescent materials from Thomson Reuters and Proquest Dialog and utilizes Thomson Data Analyzer，TI and INNOGRAPHY to analyze the patent data.Based on patent analysis，the current situation and development direction of rare earth luminescent materials are discussed and the technoloogy development direction and market arrangement of main countries in this field are analyzed，also compares technical distribution and direction，competitive structure，technique intensity and market strength.The results show that China lead the number of patents of rare earth luminescent materials，USA and Japan hold advantage in patent quality.In addition，the research and development direction about rare earth luminescent materials of China is single，but the cross-over study among the USA，Japan and Korea is existing extensively，such as glow-phosphor composition，scintillator composition，β-Sialon rare earth luminescent and nanometer rare earth luminescent material etc.Chinese enterprises should utilize the policy advantages of energy-saving lighting engineering and focus on high technology in this field，and should take the advantages of rare earth ore and enhance the research and development about rare earth luminescent materials related yttrium.
