Abstract
Optical transitions in Aluminium nitride (AlN) epilayers were studied using deep ultraviolet picosecond time-resolved photoluminescence spectroscopy. Using metalorganic chemical vapor deposition on sapphire substrates AlN epilayers of high optical qualities were obtained. Photoluminescence measurements revealed the recombination lifetimes of free exciton transitions and donor bound excitons were around 50 and 80 ps respectively.
