In-situ sol-gel synthesis of nanophosphors M2Y8(SiO4)6O2:Eu3+(M = Ca, Sr) derived from novel crosslinking reagents as silicon sources.
M2Y8(SiO4)6O2:Eu3+(M = Ca, Sr) nanophosphors were synthesized using sol-gel technology by adopting eight different kinds of silicon sources of novel crosslinging reagents. X-ray diffraction and scanning electronic microscopy show that these materials have sizes of 20-80 nm with different configurations due to the diversity of the silicate sources. Some nanophosphors present the regular microstructure despite high temperature thermolysis. In addition, all these nanophosphors exhibit strong emission at 618 nm.
