Matrix-inducing synthesis and luminescence of novel unexpected coral-like morphology Mg2Gd8(SiO4)6O2:Tb3+ nanophosphor from in situ composing multicomponent hybrid precursors

Mg2Gd8(SiO4)6O2 doped with Tb3+ was in situ synthesized by a novel hybrid precursors assembly sol–gel technology. The particle size of luminescent materials is in the range of 60–100 nm characterized by XRD and especially SEM shows that there exist some novel unexpected morphological structures owing to multicomponent hybrid precursors. The photoluminescence property of Mg2Gd8(SiO4)6O2:Tb3+ was compared to investigate as a function of Tb3+ ions concentration, which revealed that these nanophosphors showed a strong green emission from 5D4 to 7F5 at 543 nm.
