Abstract
In this study, we provide the spectra data of borophosphate zinc tungstate glasses doped with Sm3+or Dy3+ ions based on alkali and mixed alkali oxides. In order to describe the spectroscopic properties of the manufactured Sm3+ and Dy3+ glasses, we used XRD, EDAX, FT-IR, FT-Raman, Absorption, and PL Spectra. The amorphous nature of glass has been studied by looking at its X-ray diffraction data. Glasses that have been doped with Sm3+ and Dy3+ ions have been shown to exhibit significant absorption bands at 401 nm in the Vis-NIR range, as well as three weak bands at 360, 373, and 473 nm, and bands centered at roughly 1079, 1216, 1363, and 1455 nm in the NIR area. Multiple absorption bands at various wavelengths, from 796 nm to 1667 nm, are present in both series C and D glasses. After being excited at 402 nm, the emission spectra of Sm3+ doped glasses show three emission transitions at 562, 598, and 645 nm. The transition at 598 nm has been proven to produce brilliant orange-red light. Excitation at 350 nm in the emission spectra of Dy3+ doped glasses causes three emission transitions to occur at 482, 574, and 664 nm. The 574 nm emission band offers the clearest evidence of yellow emission. Energy level diagrams have been used to describe the emission process that occurs in these glasses.
