Wafer‐Scale Top‐Down Patterning of Metal Halide Perovskites

Advanced Materials Technologies, EarlyView.
Wafer‐scale patterning of metal halide perovskite films is demonstrated on 150 mm substrates using a chemically amplified resist, polymethyl methacrylate (CAR‐PMMA) and a single reactive ion etching step. The streamlined process preserves film luminescence while defining submicrometer features across the full wafer, enabling dense, scalable integration

Crossover From Excitonic to Bulk Emission in Metal Halide Perovskite Nanocomposites

Advanced Optical Materials, EarlyView.
A transition from excitonic to free‐charge recombination is uncovered in perovskite nanocomposites as a function of nanostructure size using PLQY(R, F) mapping as a function of excitation fluence (F) and repetition rate (R). These findings demonstrate that PLQY(R, F) mapping serves as a powerful and non‐invasive tool to extract quantitative information
