Abstract:We report the detailed temperature-dependent characteristics of Dy3+ doped SrAl2O4 phosphor. The phosphor synthesised using precipitation method was annealed at three different temperatures, specifically 800ºC, 900ºC, and 1000ºC. The three samples were analyzed using XRD, SEM, TEM, RAMAN, and FTIR. The observed photoluminescence emissions were consisting of peaks arising from the host SrAl2O4 as well as the dopant Dy3+. The crystallite sizes were found to be 27.22nm, 29.74nm, and 31.24nm, respectively, wit… Show more
