| 摘 要： | 利用聚合物分散液(PDLC)关特性并与同化荧光材料的特性相结合,制备出一种新型的、具有荧光效应并且荧光激发可由电场调控的荧光开关.用蓝色LED入射到开关器件,通过调制施加在开关上的驱动电压,当光开关关闭时可阻挡蓝色LED光通过,抑制荧光的产生,当光开关开启时,可在散射光路中探测到明显的荧光产生.实验发现,驱动电压在0～...

| Abstract: | Based on the switch effect of polymer dispersed liquid crystal(PDLC) and characteristics of solidified fluorescent material,a novel fluorescent switch is prepared.The fluorescent excitation effect of the switch can be modulated by electric potential.The blue LED light entered the fluorescent switch,and an ac electric field was applied on PDLC for modulation.When the fluorescent switch was in off-state,the blue LED light was inhibited.When the fluorescent switch was in on-state,the fluorescent li... |
