چکیده انگلیسی
This paper reports on the comparative investigation of the spectroscopic properties of the Y3Al5O12 (YAG) and Y3Ga5O12 (YGG) doped with Eu3+ synthesized by the combustion method. A pure phase was identified for the YGG phosphor, but one other phase was observed for the as-prepared and annealed YAG phosphor. A high intense red color emission was observed from Eu3+ doped YAG compared to the orange-red color of Eu3+ in the YGG phosphor. The optimum Eu3+ concentration was found to be higher in the YGG compared to the optimum Eu3+ concentration in the YAG. A spectroscopic investigation on the concentration quenching effect and the covalency of the Eu-O bond were carried out on the basis of the substitution of Ga3+ and Al3+in the garnet host. Judd-Ofelt parameters, different spectral and colorimetric parameters were estimated theoretically from the experimental curves, for both the hosts to determine the better luminescence media.
