In this work, the combination of three different thermal lens spectroscopic methodologies was used to better determine the fluorescence quantum yield and to observe the concentration quenching in Yb3+-doped binary tellurite ...

The fluorescence quantum yield is a measure of the efficiency of photon emission and quantifies the luminescent performance of a given sample. The determination of fluorescence quantum yields, particularly in scattering ...

The measurement of chlorophyll fluorescence in remote way represents a tool that is becoming increasingly important in relation to the diagnosis of plant health and carbon budget on the planet. However, the detection of ...

The UV absorption and fluorescence soectral bands of 2-benzoxazolinone and 6-methoxy-2-benzoxazolinone have been recorded in solution at room temperature. The phosphorescence spectral bands, their Quantum yields and mean ...

This paper describes the synthesis of new quinoline derivatives, molecules that has been long interest in the organic and medicinal chemistry. Through the Multicomponent Reaction (MCR), an important tool in modern synthetic ...

Fluorescence is commonly exploited to probe microscopic properties. An important example is tryptophan in protein environments, where variations in fluorescence quantum yield, and in absorption and emission maxima, are ...

A simplified methodology to acquire steady-state emission spectra and quantum yields of highly absorbing samples is presented. The experimental setup consists of a commercial spectrofluorometer adapted to transmission ...
