This work studies luminescence from monocrystalline gold flakes down to 13 nm thick. It reveals this signal is photoluminescence, with signals reproduced by density functional theory, resolving a decade-old puzzle.

Chiral recognition of amino acids with luminescence, despite its advantages, is usually slow and lacks generality. Here, the authors demonstrate that L-phenylalanine derived benzamide can manifest the structural difference between the natural, left-handed amino acid and its right-handed counterpart via the difference in room-temperature phosphorescence, irrespective of the specific chemical structure.

Accessing longer-wavelength emitting organic fluorophores is critical for diagnostic imaging. Here a series of silicon-RosIndolizine fluorophores with emission maxima at 1,300 nm, 1,550 nm and 1,700 nm were synthesized. The fluorophores generate high-resolution in vivo fluorescence images in mice and establish design principles for future shortwave-infrared fluorophore designs.

Advances in fluorescence microscopy and spectroscopy show their promise for applications that complement in situ structural biology methods like cryoelectron tomography.

Spectral shifts in transient photoluminescence measurements performed with a confocal microscope allow tracking of charge carrier mobilities in polycrystalline halide perovskites.

Researchers explore the unique and puzzling photostability of DNA FluoroCubes. Moreover, they improve the probes’ performance and highlight their diverse applicability.

A colorful approach to tackle the lattice mismatch in a nanocrystal

A frequency filtering method can efficiently remove the autofluorescence background and light scattering during in vivo visible and near-infrared experiments.
