The useful life curves of gan - based blue led with al2o3 and sic substrate is fit single exponential function [ i = i1 + i2exp ( - t / ) ]. fron this function, we could get aging information of led about stable inteneity 1, decay intensity i2 and decay time. the novel method of evaluating aging properties of leds was put forward
用單指數函數擬合了發光二極體的光衰減曲線[ i = i _ 1 + i _ 2exp （ t / ） ] ，這個關系式可以給出三個信息：穩定光強、衰減光強、衰減速度，提出了更加合理的評價led老化性能的方法。Life time of mn2 + in nano - zns was measured and was found to be close to that of the bulk materials. therefore the quenching centers quench the exciton but not the mn2 + ion self. 2. the increasing curves are different in film and ethanol colloids because there is diffusion process of quenching centers in colloids
對薄膜樣品的熒光增強曲線的擬合表明，顆粒表面猝滅中心數目隨輻照時間的衰減函數是非e指數形式;同時考慮溶液中猝滅中心通過向顆粒表面的擴散而逐漸耗盡，很好地解釋了溶膠的增強曲線與固體薄膜的增強曲線的不同。
