    Abstract:
    The concentration dependent luminescence properties of Nd(3+) ions doped lead calcium zinc sodium fluoroborate (LCZSFB) glasses were prepared via a melt quenching technique and reported through optical absorption, NIR luminescence and lifetime measurements. The optical transition properties of Nd(3+) ions have been analyzed using Judd-Ofelt theory. The present glasses have high stimulated emission cross - sections, entail that they have high potential laser applications. The decay curves of all the glasses show single exponential behavior. The discrepancy between the experimental and calculated lifetimes of emitting level was ascribed to energy transfer through cross-relaxation. The estimated values of radiative and saturation intensity of (4)F3/2→(4)I11/2 transition indicates the favorable lasing action at 1.06μm.
