Study of Ultraviolet Emission Spectra in ZnO Thin Films
Photoluminescence (PL) of ZnO thin films prepared on c-Al2O3 substrates by pulsed laser deposition (PLD) are investigated. For all samples, roomtemperature (RT) spectra show a strong band-edge ultraviolet (UV) emission with a pronounced low-energy band tail. The origin of this UV emission is analyze...
