Luminescence and optical studies on magnesium silicate doped with Ce3+.

Phosphors are gaining attention in the scientific and industrial world due to their potential application in various sectors ranging from display devices to LED applications. Hence, the present study focuses on morphological, structural and optical studies of magnesium silicate (MS) and Ce doped (0.1 and 1%) magnesium silicate (MS: Ce) phosphors prepared via the sol-gel method. The phase identification carried out using X-ray diffraction analysis (XRD) confirmed the formation of the orthorhombic crystal structure of Mg2SiO4(Forsterite) in MS and MS: Ce. Agglomerated impurity free morphology was identified in MS and MS: Ce using Scanning Electron Microscope (FESEM) attached with Energy Dispersive X-ray spectroscopy (EDS). The bandgap measurement verified concentration-dependent modification in the bandgap due to Ce doping. Photoluminescence emission studies (PL) confirmed green emission of 5D-2F5/2 and 5D-2F7/2 transitions at 496nm and 519nm, respectively. [ABSTRACT FROM AUTHOR]
