Excitation dynamics of the 1.54 m emission in Er doped GaN synthesized by metal organic chemical vapor deposition

Abstract

The authors report on the excitation dynamics of the photoluminescence PL emission of Er doped GaN thin films synthesized by metal organic chemical vapor deposition. Using the frequency tripled output from a Ti:sapphire laser, the authors obtained PL spectra covering the ultraviolet UV to the infrared regions. In the UV, a dominant band edge emission at 3… (More)
