With the addition of KCl, infrared cut-off wavelengths almost remained constant, but the short-wave absorption edges shifted towards shorter wavelength next to the visible transmission spectra. 随着KCl的加入，玻璃的透红外截止波长没有变化，短波吸收限向短波移动。
The results showed that Franz Keldysh effect of ZnS thin films resulted from electroabsorption of band tail. The shift of absorption edge to long wavelength was due to increase of absorption of local states near band edge. 在电场作用下，ZnS薄膜的Franz－Keldysh效应主要发生在带尾附近，带尾的局域态吸收受电场的影响引起的增加导致光学吸收边的红移。
The absorption edge positions and PL peaks shift towards shorter wavelengths while Raman spectra show broader peaks with decreasing Si layer thickness. The results are mainly attributed to the quantum confinement effects. 结果表明 ,随纳米Si层厚度的减小 ,光学吸收边以及光致荧光峰发生明显蓝移 ,Ra man峰发生展宽 ,即观测到明显的量子尺寸效应
A blue-shift of the optical absorption edge was observed from the UV-Vis transmission spectra. UV-Vis透射光谱中观察到光吸收边相对于体相半导体有明显蓝移.
