Using a narrow line output of tunable pulsed dye laser, the inhomogeneously broadened absorption band of 4I9/2→4G5/2 in Nd3+ doped germate, silicate, phosphate, fluo-rophosphate and fluoroberyllate glasses were selectively excited at low and room temperatures. Wavelength dependence of fluorescence decay were observed to investigate the decay nature and interaction of Nd3+ ions at different site in different glass hosts.
