Abstract

In this report, we investigated a single-step process for formation of high crystallinity Y₂O₃:Eu³⁺ red nanophosphor by flame spray pyrolysis (FSP) without post-heat treatments. Crystallinity of as-formed nanophosphor particle was improved by addition of urea to the nitrate-based liquid precursor. Urea increased the temperature in the flame zone thus ensuring Y₂O₃:Eu³⁺ formation at higher flame temperature. Higher temperature reached during combustion of urea promoted the formation of better crystallinity, nano-sized and spherical-shaped particles. The effect of urea in the precursor to obtain high-efficiency Y₂O₃:Eu³⁺ nanophosphor was studied.
