Flexible Thin Film UV-Induced Perovskite-Based Lighting Device

UQ research team has developed perovskite-MOF glass composite material with improved optical properties and stability. This composite is manufactured using scalable and cost-effective solid-state processing techniques. Compared to pure metal halide perovskite, UQ’s composite exhibits orders of magnitude brighter photoluminescence, with a high quantum yield and enhanced light emission. The material demonstrates exceptional stability, maintaining photoluminescence for over 10,000 hours underwater and more than two years in ambient temperatures. Additionally, the composite is resistant to heat, organic solvents, and mechanical stress, and it stabilises in a functionally favourable crystal phase. These properties make it suitable for practical applications in photocatalysis and white light-emitting diodes (LEDs). Our technology addresses significant barriers faced by metal halide perovskites, such as polymorphism, stability, heavy metal leaching, and deep trap electronic states. The composite material also provides in situ heavy metal sequestration, further enhancing its practical utility. This innovation is protected by national phase patents and is available for licensing, investment, and collaborative research opportunities.
