This article describes a new technique for postsynthetic doping/alloying of Mn into ZnSe nanocrystals. The key feature is that it employs diethyldithiocarbamate anion to selectively bind the host cations and promote ion exchange. The presence of Mn in the product is confirmed with photoluminescence (PL) and total reflection X‐ray fluorescence spectroscopy. The cation exchange reaction takes place...
The problem of light scattering by small particles is commonly solved today by the extended boundary condition method (EBCM) that uses expansions of the fields in terms of wave functions. The method is known to have a limited range of applicability. We analytically study the method in the case when spheroidal functions are applied. We find the conditions under which such a version of the EBCM method...
The problem of light scattering by a non-spherical obstacle is most often solved today by the SVM, EBCM and PMM methods applying the field expansions in terms of wave functions. The methods are based on quite different formulations of the problem and hence were earlier discussed separately. We demonstrate tight relations of the methods and present some results of our recent theoretical and numerical...
Several popular exact methods of the light scattering theory, namely the separation of variables, extended boundary condition and point matching ones, involve (single) expansions of the fields in terms of wave functions. So far the spherical functions were basically applied within these methods. We consider the main features of application of the spheroidal functions in the general case of non-spheroidal...
