Thermo and Photoluminescence of Silicate Laser Glass Doped with Neodymium
Abstract
The luminescence and thermoluminescence have been measured in vitreous materials doped with Nd3+. The luminescence spectra show a maximum at 400 nm and a shoulder at about 440 nm. The measured global thermoluminescence shows a broad band with a maximum at 270 degrees centigrade, which suggests a continuous distribution of electron traps induced by ionizing radiation. Thermoluminescence measured through two optical filters which transmit at about 400 nm and 440 nm wavelength shows a structured behavior with two glow peaks at 270 degrees centigrade and 330 degrees centigrade. This apparently contradictory behavior has been explained by the existence in this material of a continuous distribution of trap levels and a discrete distribution of recombination levels.
