• • The perovskite QDs embedded in nanoporous glass exhibit exceptional stability against water, photo, and thermal stress, attributed to strong Pb–O–Si chemical bonding at the interface, which is critical for long-term operation in humid or high-temperature sensing environments.
• • The emission wavelength of the perovskite-glass composite can be precisely tuned across the visible spectrum from 440 nm to 760 nm, enabling color-tunable luminescent sensors and display applications with a wide color gamut.
• • By integrating green- and red-emitting perovskite NG onto a blue LED chip, stable white LEDs (WLEDs) were successfully fabricated, demonstrating the practical utility of this material system in solid-state lighting with potential for high color rendering index.
• • The synthesis method employs a nano-confined aqueous approach with Pb2+ anchoring, which facilitates uniform incorporation and crystallization of perovskite QDs within the porous glass matrix, overcoming challenges of precursor infiltration and aggregation seen in other porous hosts.
