Stabilizing TiO2/CsPbI2Br Perovskite Buried Interface for All‐Inorganic Perovskite toward Highly Efficient Photodetectors

open access: yesAdvanced Materials Interfaces, EarlyView.
Polyvinyl pyrrolidone passivation enhances TiO2/CsPbI2Br interfaces, suppressing recombination and improving photodetector performance with faster response, higher photoresponsivity, and superior detectivity. Abstract Inorganic perovskites hold immense promise for optoelectronic applications, but their performance is often hindered by defects and trap ...

High‐Transmission Mid‐Infrared Bandpass Filters using Hybrid Metal‐Dielectric Metasurfaces for CO2 Sensing

open access: yesAdvanced Optical Materials, Volume 13, Issue 8, March 13, 2025.
This article presents a hybrid metal‐dielectric metasurface in transmission mode for mid‐infrared (MIR) spectroscopy. Composed of germanium on aluminium cylinders atop a calcium fluoride substrate, the metasurface achieves 80% transmission efficiency at λ = 2.6 µm with a narrow full‐width‐half‐maximum of 0.4 µm.
