Alkaline earth copper silicate-based pigments are compounds of interest from a historical point of view, thanks to their interesting near-infrared (NIR) photoemission. It is well recognized that the emission originates from the Cu2+ d-d transitions inside the chromophore group [CuO4]6-; however, the optical properties are slightly different,...

The accessible emission spectral range of lead halide perovskite (LHP) CsPbX3 (X = Cl, Br, I) nanocrystals (NCs) has remained so far limited to wavelengths below 1 μm, corresponding to the emission line of Yb3+, whereas the direct sensitization of other near-infrared (NIR) emitting lanthanide ions is unviable. Herein, we present a general...

Metal halide perovskites are one of the most investigated materials in optoelectronics, with their lead-based counterparts being renowned for their enhanced optoelectronic performance. The 3D CsPbX3 structure has set the standard with many studies currently attempting to substitute lead with other metals while retaining the properties of this...

CsPb(Cl1-xBrx)3 perovskite nanocrystals (NCs) doped with Yb3+ ions have recently attracted large attention for their applications in photovoltaics in view of the high quantum yield, exceeding 100% of Yb3+ emission at ∼1 μm. In contrast, the particularly relevant Er3+ emission at 1.5 μm in the third telecommunication window, of high interest in...
