摘要:

基于發(fā)光二極管（LED）的半導(dǎo)體照明，具有高效、節(jié)能、環(huán)保、安全等特點，是實現(xiàn)節(jié)能減排的有效途徑，代表了照明器件的發(fā)展方向。封裝材料是半導(dǎo)體照明器件的關(guān)鍵支撐材料，它不僅需要隔絕水氧以保護芯片，還需要同時具有高透光性及高折射率以提高發(fā)光二極管照明器件的光提取效率。將高折射率無機納米粒子與有機樹脂基材復(fù)合，從而提高發(fā)光二極管器件的光提取效率，進而強化照明器件的節(jié)能增效應(yīng)用，是當(dāng)前發(fā)光二極管照明器件研發(fā)領(lǐng)域關(guān)注的重點。介紹了有機無機復(fù)合材料在發(fā)光二極管封裝材料中的應(yīng)用，重點綜述了近年來高折射率有機無機納米復(fù)合封裝材料的研究進展，并結(jié)合本課題組的工作基礎(chǔ)，展望了高折射率封裝材料存在的問題和未來的發(fā)展方向。

Abstract:

Semiconductor lighting based light-emitting diode (LED), with its remarkable features of high efficiency, energy conservation, environmental protection, and safety, is an effective choice to achieve energy-saving and emission reduction, which represents the development direction of lighting devices. The encapsulation material is a key supporting material for the semiconductor lighting device, not only needs to isolate water and oxygen to protect the chip but also needs to have high light transmittance and high refractive index to improve the light extraction efficiency of the LED lighting device. The high refractive index inorganic nanoparticles are combined with the organic resin to improve the light extraction efficiency of the LED device, thereby enhancing the energy-saving effect of the semiconductor lighting device. The above-mentioned solution is the focus of current research and development of LED lighting devices. This paper introduces the application of organic-inorganic nanocomposites in LED encapsulation materials and focuses on the research progress of high refractive index organic-inorganic composite packaging materials in recent years. At the same time, combined with the work basis of our group, the problems of high refractive index encapsulation materials are analyzed and the future development direction of the encapsulation industry is prospected.
