中文拼音 [yúhuīfǎ]
余輝法
英文
afterglow method-
The long afterglow luminescent material of sr2mgsi2o7 was prepared by sintering at high temperature under the deoxidization atmosphere
首先，採用高溫固相法，在還原氣氛下制備出sr _ 2mgsi _ 2o _ 7基長余輝發光材料。The luminous intensity of phosphor - powder synthesized by this method is 32mcd / m2 after the sample was excitated 300s, and the decay time of the sample is 350min
該法制備出的發光粉激發后300s時的余輝強度32mcd m ~ 2 ，測量余輝時間為350min 。The effect of h3bo3 was discussed in detail, and the luminescence and aferglow time was increased. the stability of this material was studied and it needs coating processing in application. then by changing the base, activator, flux and reaction condition, we studied different phosphors based on the aluminates, silicates, catio3 and y2o2s in detail, and obtained the best stoichiometry and preparation of these phosphors with the colors of red, red and orange, yellow - green, blue - green, cyan and blue - purple
本論文採用高溫固相法，對黃綠色sral _ 2o _ 4 ； eu ， dy長余輝材料的發光特性進行了深入的研究，詳細討論了助熔劑硼酸對材料的影響，大幅度提高了該材料的余輝亮度和時間，並對該材料的穩定性進行了研究，得出使用時要進行包膜或其他防潮處理的結論。Data processing for temperature measurement based on fluorescence lifetime
熒光余輝測溫法中的數據處理The testing result of luminescent properties shows that the luminescent performance of the sample synthesized with sol - gel methods was better than the one synthesized with solid state reaction. the luminous intensity of phosphor - powder synthesized by sol - gel method is 65mcd / m2 after the sample was excitated 300s. and the decay time of the sample is 380min
對樣品余輝性能的測試結果表明，溶膠-凝膠法樣品較高溫固相法樣品余輝性能有很大提高，樣品在激發后300s時的余輝強度65mcd m ~ 2 ，測量余輝時間為380min 。分享友人
