Abstract
To understand the mechanism of excitation and the corresponding emission of prepared phosphor for solid state lighting here we discuss here the luminescence properties of Tb3+ and Eu3+ doped SrMg2Al16O27 phosphor for solid state lighting. In this work Tb3+ and Eu3+ ion is used as a dopant, and in case of Tb3+ the excitation and emission spectra indicate that this phosphor can be effectively excited by 353 nm, to exhibit bright green emission cantered at 545 nm corresponding to the f → f transition of Tb3+ ions while in case of Eu3+ phosphor can be efficiently excited by 396 and observed the emission at 597 nm and 614 nm in addition with analysis of chromaticity coordinates. All the characteristics indicated that SrMg2Al16O27:Tb3+ and Eu3+ is a good candidate for solid state lighting industry applications.
