Description

Phosphate (PKBAN: P2O5+K2O +BaO +Al2O3+Nd2O3) and fluorophosphate (PKBFAN: P2O5+K2O +BaO +BaF2+Al2O3+Nd2O3 and PKBAFN: P2O5+K2O +BaO +Al2O3+AlF3+Nd2O3) glasses were prepared with three concentrations (0.1, 1.0 and 2.0 mol%) of Nd3+ ions and their detailed luminescence properties have been investigated. Absorption spectra for 1.0 mol% of Nd3+-doped glasses have been analysed using Judd-Ofelt (JO) theory. The observed bands in absorption spectra from ground to excited states are assigned and analysed with the parameterized free-ion Hamiltonian model. The JO parameters have been used to predict radiative properties for 4F3/2 →4IJ (J = 15/2, 13/2, 11/2 and 9/2) transitions of Nd3+ ions in these glasses. The Inokuti-Hirayama model has been applied to the non-exponential behaviour of the decay profiles to investigate the mechanism involved in the energy transfer between the donors and acceptors
