主 题：M2Y2Si2O9:Eu3+ Phosphor Sol-gel Lattice Solar devices
摘 要：Down-conversion properties of Eu3+doped M2Y2Si2O9(M=Ba,Ca,Mg,Sr) phosphors have been investigated in *** phosphors were synthesized via the simple,fast and cost-effective sol-gel technique at a temperature of 950℃.Color coordinates and emission color can be altered by the varying concentration of dopant ion in *** luminescence intensity was obtained when doping 0.03 mol of Eu3+*** the excitation wavelength of 395 nm,these silicates showed strong red color,pure and sharp spectral peaks in visible region due to ~5 D0→F1-3transitions of Eu3+present in the *** of reaction temperature on luminescence was also analyzed for these *** sharp peaks in the X-ray diffraction pattern indicated the high crystallinity of prepared ***2Y2Si2O9has shown an orthorhombic crystal *** FTIR results confirmed the metal-oxygen vibrational modes available in the range of 400-1600 *** electron microscopy images have revealed that the variation of alkaline earth metal provided a very different crystal *** down conversion response of these phosphor materials can provide a great significance in the application of the coming solar devices.
