absorption edge shift的用法和样例：
- 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.
- 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.
- 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.
