光子倍增材料研究的进展

Development of Photon Multiplication Material

光子倍增材料能够吸收一个高能光子而发射一个以上可见光子 ,使量子效率大于 1 ,这无疑是提高普通荧光灯发光效率最理想的方法 ,也是开拓无汞荧光灯和等离子体显示器最需要的荧光粉。本文主要介绍近二十年来光子倍增材料的研究进展 ,特别对近年来的最新成就 ,例如 :Pr3+ 在含氧化合物中的双光子发射 ,Gd3+ — Eu3+

For the purpose of extensively raising the luminous efficiency of current fluorescent lamp and even further promoting the development of Hg\|free fluorescent lamp and PDP, Search for VUV phosphors with η q>1 is required. In other wards, more than one visible photon should be obtained perabsorbed VUV photon. The aim of this paper is to review briefly the research of photon multiplication material during the past 20 years, and to describe chiefly the new achievements up to the present.\;
