Year: 2016

Type: article

Abstract: The effects of 2-D hexagonal-lattice TiO2photonic crystal layers on the directional light extraction efficiency of low-scattering (Y1-xCex)3Al5O12(YAG:Ce3+) ceramic converters have been investigated. The hexagonal-lattice TiO2patterns were fabricated by an electron beam lithography process. The optimized yellow directional light extraction enhancement by a factor of 4.4 is achieved with a 2-D photonic crystal layer having a diameter of 430 nm, a lattice constant of 590 nm, and a height of 350 nm. A 3-D finite-difference time-domain model has also been developed to study the geometric parameters of the photonic crystal layer, yielding results that are consistent with our measured data.
