Ce3+-activated Zn3(VO4)2 phosphors were produced using the urea-assisted solution-combustion method. Analysis of their structure revealed they have an orthorhombic crystal structure, with crystallite sizes ranging from 85 to 113 nm. Rietveld refinement confirmed that the observed X-ray diffraction (XRD) patterns matched the calculated data, increasing confidence in the results. Diverse morphologies were observed in FESEM images. When excited at 340 nm, the photoluminescence emission spectra exhibited broad characteristics, with Zn2.99(VO4)2:0.01Ce3+ showing the highest intensity. This material demonstrates great potential for applications in solid-state lighting.

摘要

Ce3+-activated Zn3(VO4)2 phosphors were produced using the urea-assisted solution-combustion method. Analysis of their structure revealed they have an orthorhombic crystal structure, with crystallite sizes ranging from 85 to 113 nm. Rietveld refinement confirmed that the observed X-ray diffraction (XRD) patterns matched the calculated data, increasing confidence in the results. Diverse morphologies were observed in FESEM images. When excited at 340 nm, the photoluminescence emission spectra exhibited broad characteristics, with Zn2.99(VO4)2:0.01Ce3+ showing the highest intensity. This material demonstrates great potential for applications in solid-state lighting.
