無輻射躍遷
  • nonradiative : 非輻射的
  • transition : n 轉變,演變,變遷,變化;飛越;過渡期;【音樂】變調,轉調;【修辭學】語次轉變;【語法】轉換;【...
  1. 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

    ( 6 )研究了妮硅與妮磷系列玻璃發光特性與組份的關系,發現隨著nbzos濃度的增加, eu一o鍵共價性增強,局域環境對稱性降低,電一聲子禍合增強從而導致sd 。
  2. The activation effect of zn2 + modification, including enhancement of emission intensity, slowing of luminescence decay and increasing of quantum yields, results from the formation of zns shell outside the nanoparticles, which is passivating the surface of nanoparticles, eliminating the surface quenching centers, so as to block the nonradiative transition pathways through these kind of quenching centers

    Zn ~ ( 2 + )表面修飾在納米顆粒表面形成了zns殼層,鈍化了納米顆粒的表面,消除了表面猝滅中心,阻塞了通過表面猝滅中心進行無輻射躍遷的通道,從而使得發光強度增加,衰減變慢,量子效率提高。
  3. The increase of radiative transition rate with decreasing particle size was attributed to the lower symmetry surrounding the eu3 + ions, while the increase of nonradiative transition rate to the extra nonradiative transition channels caused by surface defects. ( 3 ) under excitation of 488 nm, temperature - dependence of emission intensity of the 5d4 - 7fj transition in nanocrystalline y2o3 : tb was studied. in nanocrystalline, there appeared two maximal intensities

    ( 3 )研究了488nm激光激發下不同顆粒尺寸的y _ 2o _ 3 : tb納米晶熒光發射強度隨溫度的變化規律,發現y _ 2o _ 3 : tb納米晶熒光發射強度在280k與590k存在兩個極大值,而體材料只在280k有一個極大值。
  4. This decrease in the defect pl intensity is probably caused by the increase of the nonradiative tunneling transition with multiphonon emission because of the increase in the density of si dbs

    缺陷pl強度的減小可能是因為隨著sidbs密度的增加,與多聲子有關的,從導帶到懸掛鍵的非輻射通道遷移的增加而引起的。
