由于厚膜中存在较强的表面相互作用，厚膜的直接跃迁禁带宽与薄膜相比发生了红移。
A thick film has a red shift of direct transition bandgap than thin films due to the strong interface interaction.
虽然硅是一种非直接跃迁半导体，但它的发光机制同样服从于直接跃迁半导体的广义普朗克辐射定律。
Although silicon is an indirect semiconductor, light emission from silicon is governed by the same generalized Planck's radiation law as the emission from direct semiconductors.
通过实验表明磷酸盐玻璃在制备过程中引进的水，与无辐射跃迁速率的增加有直接的关系。
Experimental research indicates that the water introduced during the preparation of phosphate glasses is directly responsible for the enhancement of nonradiative transition probability.
