Abstract

The green light emitting Tb3+ doped Ca3B2O6 nanophosphors have been synthesized by combustion method at 600°C, and their luminescent properties have been studied. The formation of phosphors has been confirmed by X-ray diffraction (XRD). The photoluminescence (PL) spectra show four emission peaks at 491 nm, 544 nm, 587 and 621 nm. It exhibited a strong green emission located at 544 nm. The effect of different dopant concentrations on emission intensity has also been studied. The maximum photo emission intensity of the Ca3B2O6:Tb3+ was obtained at a dopant concentration of 1.5 mol% of Tb3+.
