Abstract
Nano-sized phosphor powders were synthesized by the liquid phase method to confirm the size and morphology. By using the process, red phosphor particles with a size of 80 nm were obtained. The characteristic comparison of $Y_2O_3:Eu^{3+}$ and $YBO_3:Eu^{3+}$ was carried out and, as a result, $YBO_3:Eu^{3+}$ powders using boric salt showed an aggregated morphology and lower PL performance compared to $Y_2O_3:Eu^{3+}$.
