As a kind of lanthanide activated luminescent materials, development of rare earth activated luminescent glasses is one of the promising trends in the modern luminescence research. In the proposed work, Dy3+, Tb3+, Eu3+activated/co-activated/triple activated Mg21Ca4Na4(PO4)18orthophosphate glasses have been prepared by melt quenching technique for the first time. XRD pattern of the proposed glass sample shows amorphous nature but most intense peak is get matched with the standard ICSD database of Mg21Ca4Na4(PO4)18material. Vibrational feature if the proposed glass sample has been investigated using FT-IR analysis. SEM and EDS confirms the morphology and elemental analysis of the as prepared glass. Photoluminescence study of triple activated Mg21Ca4Na4(PO4)18glass sample shows multiple emission peaks under nUV excitations which covers complete white light emission. Other optical properties like UV-Vis DRS, refractive index of the glass and molar refraction of glass sample were investigated. Moreover this glass sample is crushed homogeneously and coated on solar cell using doctor blade method shows efficiency of solar cell enhanced by 43.33 % than the blank solar cell. These all results of the proposed sample proving its worth in the WLEDs, solar cell efficiency enhancement and smart windows applications. |
