We report the enhancement of the photoluminescence (PL) intensity of GaN-based light-emitting diode (LED) structures by using of a surface coating of polystyrene (PS)/silica (SiO2) core-shell nanospheres. PS/SiO2 core-shell nanosphere-coated LEDs show the highest PL intensity among various type LEDs.
