荧光体 meaning in English
fluorophor; phosphor
Examples
the amount of light yielded by fluors from the collisions of a β particle is diminishingly small. 荧光体粒子碰撞，发射出的光量很小，而且继续缩小。 - Recognition of anion by dual fluorescent sensor based on the intramolecular charge transfer in p - dimethylaminobenzoylhydrazine
分子内电荷转移双重荧光体识别阴离子研究 - The influence of y _ 2o _ 2s : eu phosphors fluorescent spectra , chroma and luminescence intensity is systematically studied when different concentration of europium is adulterated into different phosphors by means of xrd , fluorescent spectra analysis , time - basing spectra analysis , long - persistent fluorescent spectra analysis and so on ; the influence on y2c > 2s : eu phosphors structure , luminescence intensity and long - persistent curve is investigated when different concentration of mg24 " > ti4 " 1 " is adulterated into different phosphors , finding the most suited concentration of mg2 " * ti4 " 1 " ; base on the suited concentration of mg2 + > ti4 + , the influence rule on phosphors luminescence intensity and long - persistent curve with changing of eu + concentration is also studies . at the same time , by using rare - earths metals adulteration and theory of chroma synthesis , the possibility of sensitized buildup of phosphors and the synthesis of different color long - persistent phosphors is also researched
应用x射线粉末衍射( xrd ) 、荧光光谱、时间分辨光谱及磷光体长余辉寿命测试等综合实验手段，较系统地研究了掺杂eu对荧光体y2o2s ： eu荧光体的发光光谱、色度和发光强度的影响；研究了不同mg ， ti含量对磷光体基质结构性能、发光强度与余辉曲线的影响及其适宜的掺杂浓度；基此，研究了在给定mg ， ti含量时，不同eu掺量对磷光体发光强度和余辉的影响规律；从稀土掺杂和色度合成原理分别探讨了eu的发光敏化增强和制备不同光色长余辉磷光体的可能性。 - It is found that the exciting spectra is moving to long wave with the increasing of eu concentration , emission intensity is rising , the properity of red homochromy is becoming better because of the different quench concentration of emission levels 5do , 5dj and 5d2 - when the concentration of eu is up to 1 . 2mol % , the emission levels 5di and 5d2 is quenching
研究发现，随着eu浓度的增加，荧光体y2o2s ： eu激发光谱发生红移，发射强度增大，红色单色性变好，这是因为eu的5d0和sdl 、 5d2发射能级跃迁发光的淬灭浓度不同，当浓度1 . 2mol时，后两者因交叉弛豫引起浓度淬灭。 - 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。
