Germanium (Ge) all‐dielectric metasurfaces can be leveraged to strongly enhance the radiative emission from Ge layers grown on silicon‐on‐insulator substrates by industry‐standard processes. At room‐temperature, the narrowband photoluminescence (PL) intensity is enhanced by a factor ∼40× with respect to unstructured films.

Photodoping in Wide‐Bandgap Perovskite Solar Cells With MXenes
Ultrafast tandem spectroscopy and DFT modeling reveal the separate dynamics and the imbalance of electrons and holes in wide bandgap perovskite solar cells with MXene incorporation. The enhanced photoconversion performances of the devices are traced to photodoping, with selective hole trapping and suppressed recombination of electrons.

Spectral Condensing of All‐Dielectric Structural Colors via Cascaded Formation of Self‐Similar Beams
Standalone low‐index microscale ridges (MRs) are promising platforms for all‐dielectric structural color generation. They are compact and easy to fabricate, but their color purity trails behind that of resonator‐ or periodic pattern‐based structural color pixels.

1.5 µm Emission Properties of Erbium‐Implanted Thin‐Film Lithium Niobate
Optically active Er3+ ions are incorporated into x‐cut lithium niobate on insulator utilising a focused ion‐beam implantation method capable of sub‐100 nm precision. The implanted regions exhibit telecom‐band emission, with a reduction in photoluminescence intensity and lifetime below 50 K, consistent with pyroelectric‐field effects in the host ...
