QC Physics Objectives: To Determine the optical properties of glass by means of ultraviolet, visible and luminescence spectroscopy. Methods/Analysis: Different concentrations of dysprosiumdopedcalcium sulfoborophosphate (CSBP) glasses were produced by the melt quenching method and characterized through absorption, excitation and luminescence spectroscopy and its glassy form was ascertain by XRD. Findings: The emission spectrum of calcium sulfo borophosphate doped Dy3+ glasses displays bands at 482 nm (blue) and 572 nm (yellow) underneath excitation 350 nm, which agree to the transitions of 4F9/2→6H15/2 and 4F9/2→6H13/2 of Dy3+ respectively. The spectrum of the excitation for 572 nm emission takes numerous bands at 321 nm, 347 nm, 386 nm, 422 nm, 449 nm and 470 nm, which is in correspondence with the ultraviolet light emitting diode (320–410 nm) and blue light emitting (450–470 nm). Application: The findings show that calcium sulfo borophosphate doped with Dy3+ glasses could be certainly used as white LEDs.
