熒光猝減 的英文怎麼說
中文拼音 [yíngguāngcùjiǎn]
熒光猝減
英文
fluorescent quenching-
Life time of mn2 + in nano - zns was measured and was found to be close to that of the bulk materials. therefore the quenching centers quench the exciton but not the mn2 + ion self. 2. the increasing curves are different in film and ethanol colloids because there is diffusion process of quenching centers in colloids
對薄膜樣品的熒光增強曲線的擬合表明,顆粒表面猝滅中心數目隨輻照時間的衰減函數是非e指數形式;同時考慮溶液中猝滅中心通過向顆粒表面的擴散而逐漸耗盡,很好地解釋了溶膠的增強曲線與固體薄膜的增強曲線的不同。We consider that surface state act as quenching centers. with the irradiation, the surface state decreases and therefore luminescence of mn2 + increases. reduction of quenching centers is the result of chemical change by obtaining energy from zns excited by uv light
熒光增強的原因是由於zns基質向mn2 +離子和表面態的能量傳遞是兩個相互競爭的過程,紫外光輻照下表面猝滅中心數目不斷減少從而mn2 +離子的發光增強。
