Light output and fluorescence efficiency of polymer layers containing colloidal semiconductor phosphors based on CdSe/CdS/ZnS quantum dots

Features of Light Conversion Process with Covering Materials Containing Quantum Dots and their Application in Agriculture

“…One of the features of fluorescence developed lightconversion materials described previously [29], is the dependence of the conversion efficiency of the spectrum from the corner of the passage of the collimated sunbeam through the luminescent layer. Collimated incident angle of solar radiation is defined by the formula 15:…”

“…Earlier we have considered in [3] the problems of light efficiency of polymer layers containing the QDs mentioned. This work is devoted to the modeling the color characteristics of a monitor based on real luminescent properties of polymer materials obtained with the application of QDs.…”

Application of Luminescent Effects In CdSe/CdS/ZnS Quantum Dots for the Determination of Sulphur-Containing Impurities in Mixtures of Hydrocarbons and Oils

“…Secondly, the efficiency of radiation transformed by a phosphor layer depends on the irradiation conditions mentioned above, namely, on the ray angles incidence, which in their turn depend on the Sun declination, on daylight duration, on the scattered component share of flux and on other parameters. Studying the generic principles of fluorescence in optical layers in detail, which we have previously published in [13][14][15], determined some factors to be considered when predicting the light transformation process. As the "astronomic" aspects of solar radiation are widely known, we will use them to explain other observed patterns.…”

“…Another feature of the developed materials is a dependence of spectrum transformation efficiency on the collimated solar radiation angle when passing through the fluorescence layer. This is caused both by a change of the physical properties of light (in particular, its spectral composition), and by the efficiency of the light transformation process itself by the layer with change of incidence angle h. Problems of light transformation efficiency connected with changing light ray angle when passing through the layer have been previously considered [13].…”
