Alexandra Raevskaya,A. L. Stroyuk,S Ya Kuchmiy,Yu. M. Azhniuk,Volodymyr Dzhagan,Volodymyr O. Yukhymchuk,M. Ya. Valakh +6 more
TL;DR: In this article, the formation and growth of CdSe nanocrystals as well as the effect of various parameters of reacting mixture on the size of cdSe nanopocrystals were investigated.
Journal ArticleDOI
Vibrational spectroscopy of compound semiconductor nanocrystals
Journal ArticleDOI

Yu. M. Azhniuk,Alexander G. Milekhin,A.V. Gomonnai,Vasyl V. Lopushansky,Volodymyr O. Yukhymchuk,Steffen Schulze,Eduard I. Zenkevich,Dietrich R. T. Zahn +7 more
TL;DR: In this article, the selectivity of the resonant Raman process not only fo rt he size, but also for the composition of nanocrystals within the ensemble, is directly observed in the dependence of phonon band frequency, linewidth and shape on the excitation wavelength.
Journal ArticleDOI
Confinement-, surface- and disorder-related effects in the resonant Raman spectra of nanometric CdS1-xSex crystals
TL;DR: In this article, the Raman spectra of CdS 1-x Se x nanocrystals, embedded in a borosilicate glass matrix, were studied, and the lineshape was analyzed taking account of confinement-related phonons with nonzero wavevector, surface phonon modes, glass matrix pressure and disorder effects.
Journal ArticleDOI
Fundamental optical absorption edge and exciton–phonon interaction in Cu6PS5Br superionic ferroelastic
Ihor Studenyak,M. Kranjčec,Gy. Sh. Kovacs,V. V. Pan'ko,Yu. M. Azhniuk,I.D. Desnica,O.M. Borets,Yu.V. Voroshilov +7 more
TL;DR: In this article, the absorption edge of monocrystalline Cu 6 PS 5 Br was studied in the 4.2-505 K temperature range and two types of structural disorder affecting the optical absorption tail were studied.
