YAG:Ce,Yb Nano-phosphor Synthesized by Sol-gel Method and Its Luminescence Properties
Yb nano-phosphor with different doping concentrations was synthesized under various sinter temperature
via
sol-gel method. The morphology and structure of the resulting products were characterized by scanning electron microscopy (SEM) and X-ray diffraction (XRD). The luminescence properties of the phosphors were studied by photoluminescence spectra and lifetimes. The samples show a rise in particle size with increased calcination temperature. Under 1 000℃
pure YAG phase with an average particle size of~84 nm are obtained. The quenching concentration of Yb
3+
in the aforementioned phosphors exhibits a decrease from 10% to 5%
probably due to more homogeneous distribution of doping ions in the system of sol-gel products.
