固态阴极射线发光的发现及证实

提出了一种全新的激发发光方式——固态类阴极射线发光,利用无机半导体作为电子加速层,加速电子使之获得高能量,然后碰撞激发有机分子(小分子和聚合物)发光.蓝光是固态阴极射线发光中的特征发光,激子的离化是固态阴极射线发光中的独特过程.从固态类阴极射线发光的现象出发,通过普适性验证(利用不同的电子加速材料和发光材料,改变器件结构)、假象排除(几种可能产生类似现象的情况)及交叉证明(研究器件的发光与激发的时间特性),证实了固态阴极射线发光的客观性.

Definition and identification of solid state cathodoluminescence

The so-called solid state cathodoluminescence(SSCL) firstly proposed by us is a kind of fire-new excitation mode.After the acceleration by accelerated layer using the inorganic semiconductor,the electron has enough energy to excite the organic molecules(organic small molecule and polymer) and get luminescence by impact excitation.Blue light is the characteristic luminescence and the ionization of excitons is the unique process in SSCL.In this paper,the discovery of SSCL is introduced firstly.The SSCL are identified by ubiquitous certification(by changing acceleration material,luminescence material and structure of device),exclusion of artifacts(possibilities to result in this kind of phenomenon),and cross proof(by studying the temporal characters of luminescence and excitation of the device).
