Dy³⁺ ions infused modifier reliant boro-phosphate glasses: A promising host for W-LED demand

An exclusive set of Dy³⁺ ions incorporated Boro-phosphate glasses with different modifier ions like Sr, Mg, Ba, Li and Zn have been manufactured by quenching the melts. The optical behavior of the present glasses was explored through absorption, luminescence & lifetime studies. Physical parameters such as refractive index (RI) and density have been calculated and utilized to evaluate other parameters. The JO parameters exhibited the style Ω₂ > Ω₄ > Ω_6, and the luminescence spectra exhibited three strong transitions; ⁴F_9/2→⁶H_15/2 (magnetic dipole), ⁴F_9/2→⁶H_13/2 (electric dipole) and ⁴F_9/2→⁶H_11/2 (magnetic dipole). Lasing action characteristics such as emission cross-section, transition probability and branching ratio were projected from the JO parameters and oscillator strength values. The color chromaticity coordinates were determined using the CIE color chromaticity diagram. Lifetime analyses have been performed to comprehend the decay performance of the BPNfDy:X glasses.
