猝發過程 的英文怎麼說
中文拼音 [cùfāguòchéng]
猝發過程
英文
bursting process-
By calculated judd - ofelt parameters of the npre - 1 glass and luminescence dynamics equation, the author has get the changing curve about light intensity near 1540nm with the increase of er doped concentration. it was observed that the light intensity is the strongest when er doped concentration is 20mol % and the concentration - quenching phenomenon takes place after the concentration is bigger than 20mol %
5 )通過建立發光動力學方程,利用j - o計算得到的參數,得出npre - 1樣品1540nm處發光強度隨er3 +離子摻雜濃度的變化規律,看到er3 +離子摻雜mol濃度為20 %時發光最強,大於這個濃度后就發生了濃度猝滅效應。A unified theoretical model was given considering thermal activation, phonon - assisted absorption and nonradiative energy transfer processes. ( 6 ) the relationship between the fluorescence and the composition in niobate - silicate and niobate - phosphate glasses was studied
考慮熱激活、聲子輔助吸收過程與溫度猝滅建立了穩態動力學方程並對樣品熒光發射強度隨溫度的變化關系進行了量化解釋。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。
