          <dc:description>Photoluminescence was used to measure the bandgap of GaN as a function of temperature in the range 2--811 K, and the results were fitted to Varshni's empirical formula to obtain an expression for the dependence of the energy gap of GaN on temperature which should be generally applicable to most high-quality, unstrained GaN material.</dc:description>
