Auto-Phase-Locked Time-Resolved Luminescence Detection: Principles, Applications, and Prospects

open access: yesFrontiers in Chemistry, 2020
Time-resolved luminescence measurement is a useful technique which can eliminate the background signals from scattering and short-lived autofluorescence. However, the relative instruments always require pulsed excitation sources and high-speed detectors.

Coherent photo-induced phonon emission in the charge-density-wave state of K0.3MoO3

open access: yesNew Journal of Physics, 2019
We report on the observation of coherent terahertz (THz) emission from the quasi-one-dimensional charge-density wave (CDW) system, blue bronze (K _0.3 MoO _3 ), upon photo-excitation with ultrashort near-infrared optical pulses.

Magnetron-Sputtered Polytetrafluoroethylene-Stabilized Silver Nanoisland Surface for Surface-Enhanced Fluorescence

open access: yesNanomaterials, 2020
Surface-enhanced fluorescence (SEF) requires the absorption/emission band of the fluorophore, the localized surface plasmon resonance (LSPR) of the nanostructure and the excitation wavelength to fall in the same (or very close) spectral range.

Time-resolved surveys of stellar clusters

open access: yes, 2011
We describe the information that can be gained when a survey is done multi-epoch, and its particular impact for open clusters. We first explain the irreplaceable information that multi-epoch observations are giving within astrometry, photometry and ...
