Thermal analysis and luminescence of phospho-tellurite glass doped with NdF3

In the paper thermal and luminescence properties of phospho-tellurite glass and glass after thermal treatment doped with NdF3 were presented. The crystallization kinetic of the main crystallization peaks of glass was investigated using differential scanning calorimetry (DSC). The value of the activation energy for crystalline phase (Ec 54,21 +/- 5 kJ mol(-1)) was calculated using Ozawa-Flynn-Wall (OFW), Kissinger-Akahira-Sunose (KAS), Starink and Tang methods. The glass-ceramic was obtained by heat treatment method. The luminescence transitions from levels F-4(5/2) -> I-4(9/2) (878 nm), F-4(3/2) -> I-4(11/12) (1058 nm),and F-4(3/2) -> I-4(13/2) (1330 nm) in glass and glass-ceramic doped NcIF3 were compered.
