Polarization enhanced photoresponse of InSe 2D ferroelectric CuCrPS.

Two-dimensional CuCrPS possesses significant potential for low-power non-volatile devices owing to its multiferroic properties. Nonetheless, comprehensive investigations regarding the modulation of CuCrPS polarization for enhancing semiconductor photodetection capabilities and its potential applications in ferroelectric non-volatile devices are still relatively scarce. In this study, we present a novel, non-volatile, tunable photodetector engineered through the integration of a ferroelectric heterostructure comprising CuCrPS and InSe.

Novel SrLaAlO:Mn deep-red emitting phosphors with excellent responsiveness to phytochrome P for plant cultivation LEDs: synthesis, photoluminescence properties, and thermal stability.

Herein, novel rare-earth-free Mn-doped SrLaAlO deep-red emitting phosphors were successfully synthesized a traditional solid-state reaction method. The crystal structure and phase purity of the as-prepared samples were confirmed by XRD Rietveld refinement. Photoluminescence properties of SrLaAlO:Mn phosphors were examined in detail using photoluminescence spectra, decay lifetimes, temperature-dependent emission spectra and internal quantum efficiency measurements.
