Description

CdTe nanoparticles of ∼1 nm size have been prepared by chemical precipitation from aqueous or aqueous-alcoholic solutions. The nanoparticles were characterized by elemental analysis, X-ray diffraction, transmission electron microscopy, photoluminescence spectra, and by measuring their microhardness. It is demonstrated that precipitation from solution under highly nonequilibrium conditions can be used to prepare cadmium telluride nano crystals with a stable cubic (sphalerite) structure or clusters with a metastable structure close to that of wurtzite CdTe, depending on the process conditions

Abstract (Russian)

Химическим осаждением из водных и водно-спиртовых растворов получены наночастицы CdTe размером ∼1 нм. Полученные наночастицы охарактеризованы данными элементного анализа, рентгеновской дифракции, просвечивающей электронной микроскопии, спектрами фотолюминесценции и измерением микротвердости. Показано, что осаждение теллурида кадмия из растворов в далеких от равновесия условиях позволяет создавать в зависимости от режима нанокристаллы стабильной кубической фазы (сфалерита) и кластеры, вероятно, со структурой, близкой к метастабильной гексагональной (вюртцита)
