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.
