Synthesis, Optical and Photocatalytic Properties of ZnSe Microspheres/Nanosheets
Nano Biomedicine and Engineering, 2011 The microspheres/nanosheets of the ZnSe were prepared by solvothermal route. The morphological, structural, optical, as well as photocatalytic properties of the ZnSe products were studied. SEM and TEM results showed that morphologies of the products were

Optical humidity sensor based on a liquid whispering-gallery mode resonator [PDF]
arXiv, 2016 We experimentally demonstrate the use of a novel liquid state, whispering-gallery-mode optical resonator as a highly sensitive humidity sensor. The optical resonator used consists of a droplet made of glycerol, a transparent liquid that enables high optical quality factor, doped with rhodamine 6G, which acts as fluorescent emitter.

Two-dimensional electronic femtosecond stimulated Raman spectroscopy
EPJ Web of Conferences, 2013 We report two-dimensional electronic spectroscopy with a femtosecond stimulated Raman scattering probe. The method reveals correlations between excitation energy and excited state vibrational structure following photoexcitation. We demonstrate the method

Photodecomposition of Rhodamine 6G in Chlorinated Solvents
CHIMIA, 1989 Rhodamine 6G (Rh6G) dissolved in trichloromethane or 1,2-dichloroethane undergoes a spectral change when exposed to light. The resulting new molecule «Rh-N» is shown by NMR spectra and mass spectrometry to be deficient in two ethyl groups adjacent to ...

Plasmonic random laser on an optical fiber tip [PDF]
arXiv, 2020 Random lasing occurs as the result of a coherent optical feedback from multiple scattering centers. Here, we demonstrate that plasmonic gold nanostars are efficient light scattering centers, exhibiting strong field enhancement at their nanotips, which assists a very narrow bandwidth and highly amplified coherent random lasing with a low lasing ...

, 2007 We investigate the effects of two dimensional confinement on the lasing properties of a classical random laser system operating in the incoherent feedback (diffusive) regime. A suspension of 250nm rutile (TiO2) particles in a Rhodamine 6G solution was inserted into the hollow core of a photonic crystal fiber (PCF) generating the first random fiber ...

A conclusive demonstration of vibrational pumping and determination of SERS cross sections [PDF]
arXiv, 2005 We provide conclusive demonstration of vibrational pumping under Surface Enhanced Raman Scattering (SERS) conditions by performing anti-Stokes/Stokes ratio measurements down to 10 K using dried silver colloids, the dye rhodamine 6G and 676 nm laser excitation.

Strong coupling of localized plasmons and molecular excitons in nanostructured silver films [PDF]
, 2009 We report on the resonant coupling between localized surface plasmon resonances (LSPRs) in nanostructured Ag films, and an adsorbed monolayer of Rhodamine 6G dye. Hybridization of the plasmons and molecular excitons creates new coupled polaritonic modes, which have been tuned by varying the LSPR wavelength.
