Valence and Site Engineering Enable Efficient Broadband Near‐Infrared Emission at 960 nm in Cr3+‐Activated Forsterite

Advanced Materials, EarlyView.
This study reports a near‐infrared (NIR) luminescent material (Mg2SiO4:1.5%Cr,5%Li) with efficient (EQE = 48%) ultra‐broadband (FWHM ≈ 2413 cm−1 (226 nm)) NIR emission at 960 nm upon blue‐light excitation. This innovation addresses the low efficiency of long‐wavelength (λmax > 900 nm) NIR‐emitting materials due to the radiationless de‐activation and ...

Phase Distribution in Quasi‐2D Dion Jacobson Perovskite Dictates Ultrafast Energy Transfer and Directional Charge Transport

Advanced Materials Interfaces, EarlyView.
An efficient charge transfer and energy transfer at heterostructure interfaces is vital for optoelectronics. Quasi‐2D perovskites with varying layer thicknesses can create multiple interfaces, hindering charge transfer and energy transfer. Cesium Iodide (CsI) can help to redistribute these phases strategically, thereby enhancing energy transfer and ...
