Photophysics of Xanthene Dyes at High Concentrations in Solid Environments: Charge Transfer Assisted Triplet Formation
(Wiley Blackwell Publishing, Inc, 2018-09)
The photophysical behavior of two xanthene dyes, Eosin Y and Phloxine B, included in microcrystalline cellulose particles is studied in a wide concentration range, with emphasis on the effect of dye concentration on ...
Photophysics at Unusually High Dye Concentrations
(American Chemical Society, 2019-01)
The study of the interaction of light with systems at high dye concentrations implies a great challenge because several factors, such as emission reabsorption, dye aggregation, and energy trapping, hinder rationalization ...
Excitation-emission matrix fluorescence spectroscopy combined with MCR-ALS as a tool for the forensic analysis of similar and dissimilar sets of textile fiber extracts
(Royal Society of Chemistry, 2016-12)
Trace textile fiber evidence is found at numerous crime scenes and plays an important role in linking a suspect to the respective scene. In this work, investigations into the fluorescence of fiber dyes and fibers themselves, ...
Fluorescence Nanoscopy with Optical Sectioning by Two-Photon Induced Molecular Switching using Continuous-Wave Lasers
(Wiley VCH Verlag, 2008-02)
During the last decade far-field fluorescence microscopy methodshave evolved that have resolution far below the wavelength oflight. To outperform the limiting role of diffraction, all thesemethods, in one way or another, ...
Charge-transfer dynamics of fluorescent dye-sensitized electrodes under applied biases
(American Chemical Society, 2015-07)
The development of dye-sensitized solar cells requires an in-depth understanding of the interfacial charge-transfer dynamics that take place between dye sensitizers and semiconductors. Here, we describe a prototype system ...
Excitation Energy Transfer and Trapping in Dye-Loaded Solid Particles
(Blackwell Publishing, 2008-05)
The photophysics of several systems composed of a single dye or pairs of dyes attached to solid particles has been studied in the dry solid state at high dye concentrations taking into account light scattering and inner ...
A systematic study on fluorescence contrast in near infrared diffuse transmittance imaging with indocyanine green
(N I R Publications, 2019-06-25)
Near infrared fluorescence imaging is a sensitive, noninvasive technique for diagnostic applications in biomedical optics. The main purpose of this work is thus to explore how to improve the contrast of images obtained by ...
Glowing-in-the-Screen: Teaching Fluorescence with a Homemade Accessible Setup
(American Chemical Society, 2021-07)
Teaching fluorescence aims to deeply communicate light-matter interactions. The main fluorescence concepts are covered in undergraduate courses and are difficult to comprehend as the proper lighting conditions for seeing ...
Synthesis and Characterization of Photoswitchable Fluorescent Silica Nanoparticles
(Wiley VCH Verlag, 2008-01)
We have designed and synthesized a new functional (amino reactive)highly efficient fluorescent molecular switch (FMS) with a photochromicdiarylethene and a rhodamine fluorescent dye. The reactive group in thisFMS ...
Rose bengal in poly(2-hydroxyethyl methacrylate) thin films: Selfquenching by photoactive energy traps
(IOP Publishing, 2017-03)
The effect of dye concentration on the fluorescence, ΦF, and singlet molecular oxygen, ΦΔ, quantum yields of rose bengal loaded poly(2-hydroxyethyl methacrylate) thin films (∼200 nmthick) was investigated, with the aim of ...
