The recombination photoluminescence (PL) properties of hydrophilic colloidal CdS quantum dots (QDs) dispersed in gelatin were investigated. The average size of QDs varies from 2.4 to 4.4 nm. The size dependence of the emission peak position is define

We investigate the energy structure of colloidal CdS nanocrystals by measuring the UV–vis absorption spectra. Nanocrystals were synthesized by sol–gel method in a gelatin matrix in the size range from 2.5 to 3.9 (70.2) nm. In order to interpret t

The size dependences of the absorption and luminescence spectra of ensembles of hydrophilic colloidal Ag2S quantum dots produced by the sol-gel method and dispersed in gelatin are analyzed. By X-ray diffraction analysis and transmission electron micr

1. Being an austenite-forming element, nitrogen (up to 0.36%) hardens austenite into austenitic-ferritic steels, but significantly reduces the amount of ferrite — from 65 to 35%. The overall effect of this influence of nitrogen is to reduce the str

1. Hot-air oxidation of stamped plates of grain-oriented transformer steel E310 for the purpose of creating an electrically insulating layer (instead of painting or other methods of insulation) induces an increase of the magnetic permeability at freq

A method is described for the microspectral analysis of thin titanium-copper films on molybdenum wires. It is shown that the distribution of copper across the film thickness is irregular and that most of the film contains a small amount of molybdenum

1. Embrittlement at 475–500°C is due to the enrichment of the grain boundaries of the α-phase in nickel and to the precipitation of small particles of (apparently) the carbonitrile phase. 2. Embrittlement at 650–800°C is due to the precipitati
