Abstract
In the present work, we report the preparation of BCNO/SiO2 phosphor synthesized using a microwave-assisted method. This method allows a lower temperature and a shorter reaction time than simple heating (furnace). The phosphors were prepared from precursors containing, boric acid, urea, citric acid and SiO2 nanoparticles. To These precursors, silica nanoparticles were added at various concentrations from 0 to 5 %wt. The emission wavelength produced by the phosphor was varied by varying the fraction mass of the silica that were added to the precursors. The results showed that higher photoluminescence (PL) intensity was produced by the BCNO/SiO2 with 3 %wt silica addition. The novelty of this research is using microwave heating for BCNO/SiO2 synthesis, which is usually conducted using a simple heating method.
