磷光強度 的英文怎麼說
中文拼音 [līnguāngqiángdù]
磷光強度
英文
phosphorescence intensity-
The results indicate that in niobate glasses, as the concentration of nb2o5 increases, the covalence becomes strong, the symmetry becomes low and the electron - phonon coupling becomes strong, thus the lifetimes become short, the nonradiative transition processes and the temperature - quenching become strong and the value of crystal field parameter b20 becomes small

磷光體發光強度The adulteration of bi3 sm3 + can increase the fluorescent intensity, while dy3 + > gd3 la3 + reduce it ^ specially dy3 " 1 "
摻雜微量bi和sm使余輝強度的提高，但dy 、 la和gd則使磷光體余輝強度有所降低，其中dy較為明顯。It is found that with concentration of eu3 " 1 " increasing, the fluorescent intensity is firstly rising then falling. a suited concentration of eu3 + is found that the fluorescent intensity is highest but the chroma leans to orange
隨eu含量增加，磷光體余輝強度先增加后迅速降低，有一個最適宜摻雜濃度，此時余輝強度達到最高，但色度偏橙。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
應用x射線粉末衍射（ xrd ） 、熒光光譜、時間分辨光譜及磷光體長余輝壽命測試等綜合實驗手段，較系統地研究了摻雜eu對熒光體y2o2s ： eu熒光體的發光光譜、色度和發光強度的影響；研究了不同mg ， ti含量對磷光體基質結構性能、發光強度與余輝曲線的影響及其適宜的摻雜濃度；基此，研究了在給定mg ， ti含量時，不同eu摻量對磷光體發光強度和余輝的影響規律；從稀土摻雜和色度合成原理分別探討了eu的發光敏化增強和制備不同光色長余輝磷光體的可能性。In the process of study, by a lot of experiments for analyzing luminescent properties " affecting factors, such as concentration ce and tb h3bo : i, synthesizing temperature and temperature reserving time, reducing condition, etc, it gives out a good foundation for synthesizing ideal rare earths luminescent materials activated by ce and tb in aluminates strontium host. the study indicated that photoluminesent aluminates strontium power activated by ce, tb, in sral., 0, has a better luminescent effect. under the appropriate condition, srall. 0 ( that produce olivine light can be composed in 235nm or 365nm ul traviolet radiat ion act i vated by tbi07, al, > 0. i and srco : !
研究表明，鈰、鋱共激活鋁酸鍶基光致發光粉體發光效果比較好；將tb _ 4o _ 7 、 srco _ 3和a1 _ 2o _ 3為原料，在適當的條件下可以合成在235nm或365nm紫外光激發下發出較強綠光的sral _ 2o _ 4 ： （ tb ）發光粉；加入ceo _ 2合成sral _ 2o _ 4 ： （ ce ， tb ）可以增強sral _ 2o _ 4發光粉體的發光性能：在合咸溫度下保溫時間對合成樣品的發光效果有重要影響；隨實驗條件的改變可以制備出發紅、黃、綠色光的磷光體；通過x射線物相分析法對合成物的物相組成進行測定。分享友人
