Abstract
Two-dimensional (2D) triangular-lattice air-hole nanoarrays of either SiO2 or SiNx were fabricated with nanosphere lithography as photonic crystal layers (PCLs) on sol-gel derived Y2O3:Eu3+ thin-film phosphors (TFPs). The effects of varying the air fill factor of the 2D PCLs on the light extraction efficiency of the TFPs were investigated. The integrated and normally directed photoluminescence extraction efficiencies were found to be improved by coating with 2D SiNx PCLs by factors of above 5.9 and 9.4, respectively; the 2D SiNx PCLs perturb the guided light more effectively than the 2D SiO2 PCLs because of their larger refractive index contrast.
