A novel solution method to control the diameter of ZnO nanorods is reported. Small diameter (2-3 nm) nanorods were synthesized from trihexylamine, and large diameter (50–80 nm) nanorods were synthesized by increasing the alkyl chain length to trido

Nanocrystals of the wide band gap semiconductor zinc oxide of controllable morphologies were synthesized by a simple thermal decomposition method. The predominating factor in determining the morphology (spheres, triangular prisms, and rods) was the s

The composition and size of optically active CdxZn1KxSe/ZnSe quantum dots are estimated with a previously developed method. The results are then compared with those obtained for CdxZn1KxSe/Zn0.97Be0.03Se QDs. We show that introducing Be into the barr

The optical properties of CdSe/Zn0.97Be0.03Se and CdSe/ZnSe quantum dots (QDs) are investigated using photoluminescence (PL) and PL excitation spectroscopies. We show that the addition of Be into the barrier enhances the Cd composition and the overal

We discuss properties of cw and time-resolved photoluminescence (PL) as well as photoluminescence excitation (PLE) from co-doped ZnSe:Cl,N samples. These samples are characterized by the presence of the potential fluctuations due to charged donors an

In this paper we show that a multilayer Zn-Se-Te system, grown by molecular beam epitaxy in such a way as to contain sub-monolayer quantities of Te (so-called delta-doped ZnSe:Te), exhibits optical properties consistent with the presence of quantum s

We propose a self-consistent quantitative fluctuation theory of donor-acceptor pair luminescence in compensated semiconductors at constant excitation. The theory succeeds in explanation of main peculiarities of luminescence, including lineshape and p

We investigate triple-delta-doped ZnSe:Te samples grown with different Te/Zn flux ratios using timeresolved photoluminescence (TRPL). We show that the properties of the TRPL of both samples are consistent with the presence of quantum islands with a t

We present photoluminescence (PL) studies of Cl-doped Zn1−xBexSe (x=0–0.029) alloys performed in wide ranges of temperature (10– 296 K ) and of excitation intensities. We show that the high-temperature PL is characterized by a free-to-acceptor-
