Blue shifts of absorptionedges of the nanocrystallines were observed in both the ultra-filtrated acidic and alkaline sols.
对其光吸收谱测量发现，超细过滤后酸性和碱性溶胶溶液中晶粒的带边光吸收能量均有明显蓝移。

The optical absorptionedges red-shift along with the increase of annealing temperature under nitrogen and blue-shift under air were observed, which can be attributed to the quantum size effect.
在氮气和空气中退火时，随退火温度升高前者表现为红移而后者表现为蓝移，这归属于量子尺寸效应。

Blue shift appears both on the absorb edges in the absorption spectra and on the band-edge emission in the luminescence spectrum.
