Here, europium-doped (1 to 11 mol%) and titanium (1 to 5 mol%)co-doped SrY 2 O 4 : Eu phosphors were synthesized using solid-state reaction method. The synthesized samples were characterized using X-ray diffraction (XRD), field emission scanning electron microscopy (FESEM), Fourier transform infrared spectroscopy (FTIR), and photoluminescence (PL) techniques for structural, morphological, functional group, and photoluminescence studies, respectively. XRD patterns confirmed the formation of pure phase SrY 2 O 4 at 1300 C and structural parameters were further determined using Rietveld refinement. FESEM micrographs revealed that doped and co-doped samples had different morphological features. All the samples were excited at ultraviolet light excitation and emission spectra consisted of peaks corresponding to the Eu ions. The maximum PL intensity was observed for 9 mol% of Eu ions and 3 mol% codoping of Ti ions. The synthesized phosphors have potential applications in optoelectronics and display devices.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
