PL analysis of RE3+ doped Mg2SiO4 nanophosphors for display devices: Characterization and PL properties of Eu3+ and Sm3+ doped Mg2SiO4 nanophosphors for red light-emitting display devices
A simple and low-cost solution combustion method was used to prepare Eu3+and Sm3+ (1-11 mol%) doped Mg2SiO4 nanophosphors at 350 oC using metal nitrates as precursors and ODH as fuel. The final products were well characterized by Powder X-ray Diffraction, Fourier Transform Infrared spectroscopy, scanning electron microscopy and DRS. The PXRD patterns of the as-formed products show single orthorhombic phase. The crystallite size was estimated using Scherrer’s method and found to be in the range 20-25 nm. The effect of Eu3+ and Sm3+ cations on the luminescence properties of Mg2SiO4:RE3+ nanoparticles were understood from the luminescence studies. The Commission International de I’E’ clairage (CIE) chromaticity coordinates were calculated from emission spectra, the values (x,y) were located in red region. The correlated color temperature (CCT) was calculated and found that the prepared phosphor is useful for red light-emitting devices.
