Structural and photoluminescence properties of Zn[sub 2]SiO[sub 4]:Tb[sup 3+] & Zn[sub 2]SiO[sub 4]:Tb[sup 3+]+Li[sup +] phosphors

Here, we report on the synthesis and analysis of Zn2SiO4:Tb3+ & Zn2SiO4:Tb3++Li+ novel powder phosphors by using a sol-gel technique. Thermal and structural properties of the host phosphor has been carried out from the measurement of its TG-DTA, XRD and FTIR profiles. Excitation and emission spectra of these green luminescent phosphors have been analyzed in evaluating their potential as luminescent screen coating phosphors̤
