Abstract
Photoluminescence (PL) and PL excitation spectra from Eu3- implanted thermal growth SiO2 thin films have been investigated at room temperature. After annealing at 1000 °C in N2, the red light emission from Eu ions doped SiO2 film, corresponding to the 5D0-7FJ transition of Eu3+, was observed. With increasing the annealing temperature (Ta) to 1200 °C, a strong blue light emission band centered at around 450 nm appears. The conversion of Eu3+ to Eu2+ is discussed.
