چکیده انگلیسی
A serial of glasses samples with the higher ZnO concentration from 30 mol% to 45 mol% were prepared and their optical absorption and photoluminescence properties were investigated. It is shown that the composition of glass strongly affects the position of the absorption edge and emission band where a fairly big red-shift was observed with increasing of ZnO concentration. It is most likely attributed to the reduced quantum confinement effect due to increased aggregation degree of ZnO in the glass matrix. The introduction of F− into zinc barium silicate glasses leads to a notable red-shift of the absorption spectra, as well as the enhanced UV emission and distinctive visible emissions.
