摘要

Nanocomposite layers containing In2O3 quantum dots (QDs) with radii ranging from 1.8 to 5 nm embedded in SiO2 matrix were prepared. Prominent blueshift with a drastic increase in emission efficiency for red, green and blue emissions were observed in the photoluminescence (PL) spectra of samples when QD radius was less than 1.32 nm. PL enhancement was further confirmed by the calibration of defect trap levels and indicated the Bohr radius of In2O3 QDs was 1.32 nm.
