    • Abstract

       

      The simple method for the preparation of phosphors such as aluminates, Y2O3, YVO4 and LaPO4 by the combustion synthesis described earlier in the literature is reported. It is shown here that the phosphors prepared by such synthesis do not possess all the required characteristics. Suitable modifications by way of annealing at >1200°C in controlled atmospheres, however, can yield the phosphors with characteristics which may fulfil the demands of lamp industry.
