Multi-resonant Au/Si particles exhibit unique photoluminescence spectra, enabling creation of physical unclonable functions with sub-diffraction-limited critical sizes.

Raman spectroscopy articles from across Nature Portfolio Raman spectroscopy is an optical technique that detects intrinsic vibrational, rotational and other low-frequency modes in molecules upon ...

Operation is simple. Just load the sample into the sample chamber. Then enter a few conditions on the measurement software to measure the fluorescence lifetime and photoluminescence (PL) spectrum.

Abstract: All PV modules must maintain their performance for years once deployed in the field. Understanding the impact of new processing and materials on the long-term reliability of panels is thus ...

We investigate the dynamical properties of photoexcited carriers in a single monolayer of graphene at room temperature in air using femtosecond time-resolved luminescence spectroscopy. The ...

The simultaneous integration of a nematic liquid crystalline structure and light emission in a photonic material is attractive for designing novel optical devices. Here we describe the luminescent ...

The optical properties of few-layer (FL) GaSe are investigated using thickness- and temperature-dependent Raman scattering and photoluminescence (PL) spectroscopies. The vibrational modes exhibit ...
