The Cr3+ activators have been adopted to produce desired near-infrared broadband
emission via ligand field engineering by choosing hosts with appropriate sites. First …

Traditional light sources, eg, incandescent and fluorescent lamps, are currently being
replaced by white light-emitting diodes (wLEDs) because of their improved efficiency …

Achromatic quarter waveplates (A-QWPs), traditionally constructed from multiple birefringent
crystals, can modulate light polarization and retardation across a broad range of …

Metal-halide perovskites have garnered considerable research attention as highly efficient
light emitters in recent years due to their outstanding optoelectronic properties with …

Cooperative Jahn–Teller (JT) distortion accompanied by electromagnetic lattice coupling
plays a crucial role in numerous important phenomena in materials science. The JT …

Detailed first-principles calculations have been carried out to study the stabilization,
