• • B2O3 addition to GeO2-SiO2 glass network yields CsPbBr3@Glass with 85% PLQY, enabling high-efficiency downconverters for LCD backlights; industrial impact: reduces energy consumption and extends display lifetime.
• • Glass powder content of 4% in AB glue maximizes fluorescence intensity; higher content improves blue light stability, with green samples retaining superior stability after 120 h irradiation (red samples degrade faster), critical for long-term color fidelity in displays.
• • In situ heating-cooling cycles show thermal recovery >90% for green and >86% for red CsPbX3@Glass, indicating robust reversible thermal stability essential for high-power LED applications.
• • CsPbX3@Glass@PS films maintain >90% initial PL intensity after 15 days in 95% ethanol, demonstrating dual glass-polymer protection that enables polar solvent resistance, a key requirement for solution-processed display manufacturing.
