The behavior of Nd3+ 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 NdAlO3 with simple cubic structure having a0=3.744Å occurred in the glass-forming process; (2), The values of J-O parameters Ωt(t=2, 4, 6) were an order of magnitude smaller than those in an ordinary phosphate glass; and, (3), Addition of NdAlO3 powder to potassium aluminometaphosphate glass gave a fluorescence lifetime at 1.06μm wavelength, longer than that of the same mother glass containing Nd2O3.
