Paper Abstract

We have studied the f-f absorption spectra of Er3+ in GaN crystal grown by gas phase epitaxy in chlorine system. A detailed study of 4I15/2 yields 2H11/2 transitions in the region 19000-19260 cm-1, has been carried out at 293, 77 and 2K. At T equals 2K the 4I15/2 yields 2H11/2 spectrum contains 6 lines in accordance with theoretical predictions for Er3+ in noncubic crystal field. The levels of 2H11/2 multiplet are situated at: 19041, 19049, 19074, 19108, 19191, 19246 cm-1. The number of lines observed at T equals 2K and its small width indicate that in our samples Er3+ ions occupy predominantly a unique position in GaN lattice. Most probably, Er3+ substitutes Ga atoms or enters in interstitial position.
