Spectroscopic investigation of co-formers on Dy3+ ions activated Barium comprised zinc borate glasses for enhancing the solid-state laser applications

The purpose of the existing research is to analyze the luminescence behavior on a set of different co-formers involved Dy³⁺ ions activated Barium comprised zinc borate glasses fabricated through the utilization of usual melt quenching technique with a glass composition of 64B₂O₃+20ZnF₂+15BaO+1Dy₂O₃ & 44B₂O₃+20A+20ZnF₂+15BaO+1Dy₂O₃ (where A = 0, P₂O₅, TeO₂, Bi₂O₃). Their structural, optical, luminescence and decay behavior were scrutinized by several respective characterization techniques. Some of the physical properties were calculated by utilizing the corresponding formulae. Besides, the bonding parameter and oscillator strength estimation alongside Judd-Ofelt parameter are also computed to find out the radiative properties from luminescence spectra. From these analyses, ionic nature of the glass network was confirmed. The spectroscopic intensity parameter follows the tendency Ω₂>Ω₆>Ω₄. This higher value of Ω₂ is owing to the larger oscillator strength value and signalizing that Dy³⁺ ions are completely doped into the glass network. Among all the as- quenched samples, BZfBaT:Dy glass possesses high stimulated emission cross-section and holds high optical gain width value which implies that the glass is a perfect candidate intended for laser utilization. By utilizing its emission spectra, the colour chromaticity coordinates (x, y), colour purity, colour correlated temperature (CCT), and Y/B intensity ratio were investigated by means of CIE 1931 diagram and confirmed the light emitting capability. Decay curve displays well-fitting with the exponential fit and the efficiency (ɳ) for the BZfBaP:Dy glass is found to be 61 % and possesses high optical gain signalizing that the material is a perfect choice for optoelectronic applications.
