Calotropis gigantean-assisted YSO:Pr nanophosphors: Near-ultraviolet (NUV) photoluminescence and J-O analysis for solid-state lighting solutions.

Y2SiO5:Pr3+(1–9 mol%) nanophosphors were prepared via combustion synthesis usingCalotropis giganteaplant latex as fuel. The PXRD patterns of the sample revealed a monoclinic phase with phase group P21/Cn.14. The crystallite size was found to be in the range of 40–48 nm. The effect of Pr3+cations on the luminescence characteristics of YSO nanoparticles was studied. The CIE chromaticity coordinates were located in the yellow region. Hence, the present phosphor finds applications in light-emitting diodes and display devices. [ABSTRACT FROM PUBLISHER]
