WebApr 12, 2024 · Here, we propose and experimentally realize a photon-recycling incandescent lighting device (PRILD) with a luminous efficacy of 173.6 lumens per watt (efficiency of 25.4%) at a power density of 277 watts per square centimeter, a color rendering index (CRI) of 96, and a LT70-rated lifetime of >60,000 hours. WebAlthough the record efficiency of 25.2% was achieved using a 500–1000 nm-thick perovskite film within an appropriate device structure, it is desirable to achieve high efficiency with a thinner perovskite film because the thinner layer can gain benefits of lowering Pb content, reducing cost and better adjustability for a transparent window, …

WebDec 19, 2024 · Perovskites, Thin films, X-rays Abstract We demonstrate a potential candidate, the 0D “all-inorganic” perovskite material Cs 2 TeI 6, as a sensitive all-inorganic X-ray photoconductor for the development of the new generation of direct photon-to-current conversion flat-panel X-ray imagers. WebHybrid perovskite materials have been one of the brightest spotlights in the radiation detection research fields due to their higher carrier mobility and lower trap state density in recent years. In this paper, the CsPbBr 3 microcrystal thick film is successfully prepared using a low-cost facile solution synthesis method. tela da tv samsung 40 polegadas
