    Abstract:

    A series of Nd3+- doped heavy metal oxide alumino-phosphate glass samples were synthesized by melt quenching technique. The samples were studied for their luminescent and radiative properties. UV-Visible absorption spectra show nine absorption bands owing to transitions from 4I9/2 of Nd3+-ion to 2I11/2+4D3/2+4D1/2 (356nm), 4G9/2 ( 511nm), 4G7/2 (525nm), 4G5/2+2G7/2 (582nm), 2H11/2 ( 627nm), 4F9/2 (683nm), 4S3/2+4F7/2 (746nm), 4F5/2+2H9/2 (803nm) and 4F3/2 (874nm). It has been observed that Judd-Ofelt parameters are influenced by local structure of rare-earth ions. An intense emission band observed at 1044 nm on exciting the samples at  = 808 nm has been assigned to transition 4F3/2→4I11/2. Large values of transition probability, high branching ratio and high stimulated cross-section of this transition indicates its potential use in IR lasers.
