Summary: Converting and patterning high-quality perovskite quantum dots (PQDs) into flexible thin films is important for solid-state optical applications. However, their poor stability and low quantum efficiency after film formation hinder their usability. This study demonstrates an in situ synthesis strategy to prepare long-term stable CsPb(Br0.3I0.7)(3)@poly(methylmethacrylate) (PMMA) PQDs fibers with thermal responsive fluorescence performance, which can rapidly and reversibly quench and recover between heating and cooling cycles. This temperature-reversible luminescence characteristic not only deepens the understanding of perovskite material's temperature-dependent phase transition behavior but also broadens their applications in various temperature-responsive fields.

Summary: Semi-transparent large-area luminescent solar concentrators (LSCs) are considered crucial for future zero-energy or low-energy buildings. Inorganic colloidal quantum dots (QDs) show promise as LSCs due to their tunable bandgap, large Stoke shift, and high photoluminescence (PL) quantum yield. However, long-term stability remains a challenge. This study successfully fabricates large-area tandem LSCs using highly stable carbon dots (CDs) and highly luminescent CuInSeS/ZnS QDs, demonstrating high efficiency and stability for potential building-integrated photovoltaic (BIPV) devices.
