The behavior of Nd^<3+> ions in aluminophosphate glasses was investigated by spectrophotometry, scanning electron microscopy, energy dispersive X-ray spectroscopy, wavelength dispersive X- ray spectroscopy and X- ray powder diffraction analysis . It is shown that (1) , the crystallization of NdAlO_3 with simple cubic structure having a_o = 3.744 A^^° occurred in the glass-forming process ; (2) , The values of J- O parameters Ω_t( t =2, 4, 6) were an order of magnitude smaller than those in; an ordinary phosphate glass ; and, (3) , Addition of NdAlO_3 powder to potassium aluminometaphosphate glass gave a fluorescence lifetime at 1.06 μm wavelength, longer than that of the same mother glass containing Nd_2O_3.
