Abstract

ZABB glass with 10 ZnO – 10 Al2O3 – 10 Bi2O3 – 70 B2O3 – x(%wt) Mn2+, doped with varying concentrations of Mn²⁺ (0.5–5.0 %wt), were fabricated using the melt quenching method. The samples exhibited a non-crystalline structure. Surface morphology was analyzed through SEM, and the composition of samples were confirmed using energy dispersive X–ray (EDX) spectroscopy. Photoluminescence excitation (PLE) spectra shows that Mn2+-doped ZABB glass can be excited across a broad UV range (310-450 nm). The photoluminescence (PL) spectra showed broad emission bands, with a peak at 595 nm corresponding to the ⁴T₁(G) → ⁶A₁(S) transition. The calculated color coordinates indicated red emission from the glass samples . These findings suggest that this glass material is potential for application in manufacturing W – LEDs with a high color rendering
index (CRI).
