电子释放 meaning in English

electron liberation
electron releasing
electron-releasing

The study indicate that sral2o4 : tb3 + phosphor can be composed from 1250c to 1550c , the phosphor ' s luminance reduce and the afterglow time shorten along with the compounding temperature ; the better luminance and afterglow with the better crystalloid degree ; the luminescence of tb3 + ion in the sral2o4 is coming from the transition of 5d4 - 7fj ( j = 6 , 5 , . . . . . . 0 ) ; the afterglow is because of the electron that seized in the trap released which integrate with the luminescence center
合成发光体亮度随合成温度的降低而逐渐降低，余辉时间逐渐缩短；当合成物具有较好的结晶度时，合成的发光粉不仅发光亮度高而且余辉时间长； tb ~ ( 3 + )离子在sral _ 2o _ 4基质晶格中的发光主要来自于~ 5d _ 4 ~ 7f _ j ( j = 6 ， 5 ， … … 0 )的跃迁；其余辉是因为不断有被陷阱所俘获的电子释放出来与发光中心复合。
