Abstract

We report the results of the time-resolved emission spectra and the decay curves, concerning the important green emission transition at 544 nm (⁵D₄→⁷F₅). Five other transitions at 489 nm (⁵D₄→⁷F₆), 585 nm (⁵D₄→⁷F₄), 620 nm (⁵D4→⁷F₃), 674 nm (⁵D₄→⁷F₂) and 648 nm (⁵D₄→⁷F₁) of Tb³⁺ : (La,Y)PO₄ and (La,Gd)PO₄ were measured to understand the influences of the wavelengths of excitation, in emitting green color from these two novel phosphor materials. It was observed that the spectral features possess sharp and bright emission for potential applications on the monitors of the television and some other related electronic systems, in observing the images in green color.
