Quantum dot-modified paper-based assay for glucose screening
(Springer Wien, 2016-02)
The article describes a simple optical assay for glucose. It is based on the use of paper spots loaded with colloidal CdSe/ZnS quantum dots (Q-dots) and the enzyme glucose oxidase (GOx). Circular paper sheets were uniformly ...
Photoinduced hole-transfer in semiconducting polymer/low-bandgap cyanine dye blends: evidence for unit charge separation quantum yield
(Royal Soc Chemistry, 2009-01-01)
Power-conversion efficiencies of organic heterojunction solar cells can be increased by using semiconducting donor-acceptor materials with complementary absorption spectra extending to the near-infrared region. Here, we ...

Cadmium telluride nanocrystals as luminescent sensitizers in flow analysis
(ELSEVIER SCIENCE BV, 2011)
A fully automated multipumping flow system (MPFS) using water-soluble CdTe quantum dots (QD) as sensitizers is proposed for the chemiluminometric determination of the anti-diabetic drugs gliclazide and glipizide in ...
Luminescence quantum efficiency at 1.5 µm of Er3+- doped tellurite glass determined by thermal lens spectroscopy
(Elsevier BVAmsterdam, 2013-10)
Erbium doped tellurite glasses (TeO2 + Li2O + TiO2) were prepared by conventional melt-quenching method to study the influence of the Er3+ concentration on the luminescence quantum efficiency (η) at 1.5 µm. Absorption and ...
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 ...
Characterizing some photophysical, photochemical and photobiological properties of photosensitizing anthraquinones
(Elsevier Science Sa, 2007-05)
Some photophysical, photochemical and photobiological properties of nine anthraquinones (AQs) isolated from a phototoxic plant, Heterophyllaea pustulata, were studied. The photosensitized generation of superoxide anion ...
