A new series 34B2O3+20NH4H2PO4+10Al2O3+10PbO+25MCO3+1Dy2O3, where (M= K2 and Mg) of Dy3+ doped lead-alumino-boro-phosphate glasses have been prepared by conventional melt quenching technique. The prepared glass samples were characterized through Optical absorption and photoluminescence spectra. The bonding parameter, Oscillator strength and Judd-Oflet (JO) parameter have been calculated and investigated through optical absorption spectra. The excitation and emission wavelength have been obtained through the photoluminescence spectra. The emission spectra exhibit two visible bands as 4F9/2→6H15/2 (Blue) and 4F9/2→6H13/2 (Yellow). Yellow to blue (Y/B) intensity ratio and chromaticity coordinates have been estimated for the stimulation of WLED applications. [ABSTRACT FROM AUTHOR] |
