Abstract
Nanostructured powders of Sr1.96MgSi2O7:Eu 0.01 2+ , R 0.01 3+ (R3+ = Er3+, Tm3+ and Tb3+) have been fabricated via urea combustion technique. XRD results implied that tetragonal Sr2MgSi2O7 was the major phase whereas monoclinic Sr2SiO4 and SrSiO3 were the minor phases. Meanwhile, field emission SEM textures showed the hollow spherical network-like shape structures filled with fused interconnections for the Sr1.96MgSi2O7:Eu 0.01 2+ sample. It has been recognized that the replacement of Sr2+ with co-dopant R3+ ions e.g. Er3+, Tm3+ and Tb3+ considerably help obtaining homogeneous structure as well. The values of band gap energy and calculated refractive index were ultimately dependant on the ionic radius of R3+ co-doping ion. It has been suggested that the divalent activator ion (Eu2+) was responsible for the number of PL emission spectra, while the trivalent co-activator ions (R3+) were the key reasons for variations in the broadening and intensity of PL emission spectra.
