Abstract

Ca14Zn6Al10O35:Mn4+, Nd3+ phosphors were prepared by a liquid phase impregnation method. The results of XRD, SEM, and EDS analysis confirmed that pure CZA:Mn4+ and CZA:Mn4+, Nd3+ phosphors with single phases were synthesized. The Mn4+ doped phosphors exhibited strong red emission in the range of 600 to 850 nm when excited at a wavelength of 356 nm. The luminescence properties were investigated according to changes in the concentrations of Mn4+ and Nd3+ ions. The particle sizes of the phosphor when fired at 1200 °C for 3 hours were 100 to 500 nm


Keywords: Ca14Zn6Al10O35: Mn4+, Nd3+, Starch, Red phosphor.
