Paper Abstract

Rare-Earth (RE) was implanted to GaN epitaxial layer. Eu-implanted GaN films were annealed at the temperature range of 950 - 1100°C to reduce the implantation damages. Photoluminescence (PL) properties were measured, and strong emission at 621 nm corresponding to the transition from 5D0 to 7F2 states of Eu3+ was observed. The thermal quenching of PL intensity was very small and the peak position was not shifted. Large hardness for high energy electron-induced damages was observed.
