摘要：

Visible blue-green light emission metastable gamma-Ga2O3 quantum dots were prepared, and the light emission is clearly visible to the naked eyes. The UV-visible spectra present a blueshift phenomenon of the absorption edge as the particle sizes decrease; the fitted result of UV-visible data by Tauc function shows that the as-prepared gamma-Ga2O3 is a wide-band-gap semiconductor with a direct band gap structure. The photoluminescence spectra show the evidence of quantum confinement and a blueshift when the crystal sizes decrease.
