摘要
研究对象为紫外激发的弱荧光发光材料。基于色度学原理,利用微机接口技术,结合光电转换技术,给出具体的余辉测试系统方案。使得仪器能够自动定时采集探测器的光电流,并校正成发光亮度,从而得到其余辉衰减特性曲线。
The article is about a kind of long afterglow luminous material.On the basis of colorimerty,making use of hardware interface technology and photoelectricity converting technology,the paper introduces the whole consideration of the system.The instrument can automatically collect photocurrent of the detector.After correcting the current to luminance,we got the afterglow curve of the material.
