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 ...

Sound, Force and Light Induced Emissions from Er3+‐Mn2+ Doped ZnS/CaZnOS Heterostructure for Remote Temperature Monitoring via Photo‐ and Mechanoluminescence

Advanced Materials, EarlyView.
Er3⁺/Mn2⁺ co‐doped ZnS/CaZnOS heterostructures are developed for remote temperature and force/sound sensing. The material exhibits UV/NIR photoluminescence, with energy transfer influencing color. Mechanoluminescence intensity is measured against applied power. Temperature‐dependent photoluminescence enabled luminescence thermometry.
