Description
Summary:The current investigation is aimed to provide a possible route to enhance the photoluminescence (PL) property of phosphors. In the present work, comprehensive studies were done on the structural and PL characteristics of CdSiO 3 :Eu 3+ nanophosphors co-doped with Zn 2+ . Oxalyldihydrazide (ODH) was used as a fuel to synthesize the the phosphors by employing solution combustion method. The structural studies using powder X-ray diffraction (XRD) technique confirmed that the phosphors were formed in monoclinc phase. The Debye-Sherrer’s equation was used to estimate the average crystallite sizes of Cd 0.95-x Eu 0.05 Zn x SiO 3 phosphors and were found to be in the range of 30–40 nm. The microstructure analysis of the samples showed porosity, which, increased with Zn 2+ ion concentration.The optical properties of the samples were investigated using UV–Visible and photoluminescence studies. The optical energy band gap of CdSiO 3 :Eu 3+ phosphor varies from 4.5 and 4.95 eV upon co-doping with Zn 2+ ion. The PL studies confirm that the 5 mol% Zn 2+ co-doped CdSiO 3 :Eu 3+ phosphors the intensity of the dominant peak (611 nm, 5 D 0  →  7 F 2 ) was enhanced by a factor of 2 (ie. 200%) in comparison with CdSiO 3 :Eu 3+ phosphor.
