Influence of high voltage static electric field for super - weak luminesce of crops seed 高压静电场对作物种子超弱发光的影响
2.
The adulteration of dy3 + n gd3 " 1 " ^ la3 + > sm3 " 1 " can inhance the luminesce efficiency , while bi3 + decreases 掺杂适量的dy , gd , la , sm可提高磷光体发光效率,而掺bi则使磷光体强度降低。
3.
The influence rule of y2c > 2s : eu , mg , ti long - persistent phosphor fluorescent properity and luminesce intensity is studied with the changing of concentration of mg , ti 研究了不同的mg , ti掺杂量对y2o2s - eu , mg , ti磷光体发光强度和余辉特性的影响规律。
4.
The suited concentration of mg2 + is 20mol % , and the concentration of ti takes more effect on the fluorescent intensity . base on the suited adulteration concentration of mg2 + , ti4 * , the relationship between concentration of eu3 + and phosphor luminesce properity and chroma is studied 反之, ti含量给定( 10mol ) ,随mg掺量增加也表现出类似的规律,其余辉最强处mg含量约20mol ,但ti对余辉的增强作用较mg更为显著。
5.
The influence of y2o2s : eu phosphors fluorescent spectra , chroma and luminescing efficiency is studied with the changing of concentration of eu34 " ion , and the suited concentration of eu3 + ion is acquired , all these provided support for the research on the yzc ^ s : eu , mg , ti long - persistent phosphors structure and luminescence performance 研究了不同eu含量对y _ 2o _ 2s : eu荧光体光谱性能、发光效率和色度的影响,给出了最适宜的掺eu浓度,为进一步研究探讨y2o2s : eu , mg , ti长余辉磷光体的基质组成和发光性能提供依据。
