nonradiative meaning in English
非辐射的
Examples
- The results indicate that the radiative and nonradiative rates both increase with decreasing particle size
结果表明随着颗粒尺寸的减小，辐射跃迁速率与无辐射跃迁速率都有所增加。 - 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强度的减小可能是因为随着sidbs密度的增加，与多声子有关的，从导带到悬挂键的非辐射通道迁移的增加而引起的。 - 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
考虑热激活、声子辅助吸收过程与温度猝灭建立了稳态动力学方程并对样品荧光发射强度随温度的变化关系进行了量化解释。 - 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 + )表面修饰在纳米颗粒表面形成了zns壳层，钝化了纳米颗粒的表面，消除了表面猝灭中心，阻塞了通过表面猝灭中心进行无辐射跃迁的通道，从而使得发光强度增加，衰减变慢，量子效率提高。 - 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激光激发下不同颗粒尺寸的y _ 2o _ 3 ： tb纳米晶荧光发射强度随温度的变化规律，发现y _ 2o _ 3 ： tb纳米晶荧光发射强度在280k与590k存在两个极大值，而体材料只在280k有一个极大值。
