Abstract

A comparative study of pulsed laser deposited (PLD) films and their powder precursor using low temperature photoluminescence (PL) spectroscopy and cathodoluminescence (CL) imaging is presented. The PLD films show several well-defined features in low-temperature PL. Although the free exciton transition is absent, two sharp bands appear, quite close to the band-edge, at 3.261 eV and 3.410 eV, in addition to the familiar donor-acceptor pair band near 3.2 eV and the well-known yellow band. CL imaging reveals relatively poor crystallinity of the micropowder.
