Ca2+-substitution effects in Ba9-Ca Al2Si6O24:Ce3+, Na+ phosphors
Source abstract
Abstract
Abstract The Ca2+ ion was substituted for a Ba2+ ion in Ba9Al2Si6O24 host lattice using a solid-state reaction. The solid-solubility of Ba9-xCaxAl2Si6O24 compounds was characterized using X-ray powder diffraction (XRD) for x = 0 to x = 9 according to the Hume-Rothery rule. The obtained Ba9-xCaxAl2Si6O24 hosts between x = 2 and x = 5 were examined in order to index the peak positions as a single-phase orthosilicate, which has a trigonal unit-cell. The structure of Ba6Ca3Al2Si6O24 was characterized using synchrotron XRD. The photoluminescence excitation, emission spectra, and scanning electron microscopy (SEM) data of intense blue Ba8.8-xCaxCe0.1Na0.1Al2Si6O24 (x = 2 to x = 5) phosphors were monitored. Furthermore, a comparison of the quantum efficiency of the obtained phosphors and sodium salicylate was performed.
