Abstract: Nanocrystalline terbium aluminium garnet phosphor has been prepared by the calcinations (800-1600°C) of the precursor obtained by sol-gel technique. The particle size measurements and SEM analysis of the as prepared powder show the grain size variation in 50-600 nm range. XRD and FTIR measurements show the development of better crystalline phase with increase in the sintering temperature. Photo-luminescence spectra at room temperature consist of well separated six groups around 440 nm, 490 nm, 549.9 nm, 586.9 nm, 624 nm and 691 nm. The emission intensity of the group around 691 nm increases with the increase in calcination temperature from 1000°C-1400°C, while in case of all other groups the intensity decreases in this range of temperature.
