Abstract

This paper reports the results obtained during the investigation of the emission spectra of Eu³⁺:Ca₃Ln(=Y,Gd)(VO₄) ₃ phosphors that are prepared by a chemical co-precipitation method. For these phosphors, XRD, SEM and FTIR analysis have also been carried out to understand their structural properties. When these Eu³⁺ phosphors were put under an UV source, those were in bright red luminescent. Based on the red color emission richness and also emission spectral measurements, Eu ³⁺:Ca₃Y(VO₄)₃ phosphor has been found to be a better material compared with Eu³⁺:Ca ₃Gd(VO₄)₃ phosphor. An energy level scheme has been presented to explain the emission process involved in these phosphors.
