influence of high voltage static electric field for super-weak luminesce of crops seed 高壓靜電場對作物種子超弱發(fā)光的影響
the adulteration of dy3 + n gd3 " 1 " ^ la3 + > sm3 " 1 " can inhance the luminesce efficiency, while bi3 + decreases 摻雜適量的dy,gd,la,sm可提高磷光體發(fā)光效率,而摻bi則使磷光體強度降低。
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摻雜量對y2o2s-eu,mg,ti磷光體發(fā)光強度和余輝特性的影響規(guī)律。
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含量給定(10mol),隨mg摻量增加也表現(xiàn)出類似的規(guī)律,其余輝最強處mg含量約20mol,但ti對余輝的增強作用較mg更為顯著。
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含量對y_2o_2s:eu熒光體光譜性能、發(fā)光效率和色度的影響,給出了最適宜的摻eu濃度,為進一步研究探討y2o2s:eu,mg,ti長余輝磷光體的基質(zhì)組成和發(fā)光性能提供依據(jù)。
