The recent progress and developments on perovskite photodetectors are summarized from the perspective of device physics and materials science.

The low-frequency Raman spectra of metal-halide perovskites are reported using a combination of a 976 nm laser and nanoconfinement to stabilize the crystals against temperature-induced polymorph transitions and humidity-induced degradation.

In-plane (180°) polar nano-domain and optical dispersion behavior of the KNNM0.06 film with optimal ferroelectric properties.

Higher quality Nd:GMB crystals were obtained using enhanced K₂Mo₃O₁₀–B₂O₃ flux. Intense multi-wavelength emissions reveal their potential in THz technology.

YMB and Nd:YMB crystals with excellent physicochemical properties have been grown by TSSG method. The intense multi-wavelength emissions reveal the potential of THz technology.

Three single-molecule fluorescent organic probes differing in the number of amino groups have been developed for demonstrating their effect on the highly selective and ultrafast sensing of TNP in water.

Antimony (Sb³⁺) ions are introduced to manipulate the structure and optical properties of Cs₂NaBiCl₆. New possibilities in photovoltaics and white light emission applications could be envisioned.
