Synthesis and photoluminescence of Cr-, Ni-, Co-, and Ti-doped ZnSe nanoparticles

Novel dithiols as capping ligands for CdSe quantum dots: optical properties and solar cell applications

“…When DTs were used as stabilizers, the -SH group of DT broke and sulfur was incorporated into the crude CdSe QD crystal lattice, resulting in the formation of a CdSe(S) structure. 40,41 We calculated that the grain size of QDs was 4 nm using the Scherrer equation with a fullwidth-at-half-maximum (FWHM) value of 5 based on the (1 1 1) peak of the XRD pattern. TEM images of pristine CdSe and DTcapped CdSe are shown in Fig.…”

Mid-Infrared Emission of Transition Metal Co2+-Doped ZnSe Nanocrystals at Room Temperature via Hydrothermal Preparation

“…Recently, TM 2+ -doped ZnSe nanomaterials have attracted increasing attention because of their high luminescence quantum efficiency, high optical gain with low threshold, and their potential applications in display devices, biomedical labeling, and lasers. − ZnSe plays an important role in studying semiconductor nanocrystals . In fact, over the past few years, researchers have focused on the visible luminescence properties of ZnSe nanomaterials doped with Ni 2+ , Co 2+ , , Fe 2+ , , and Mn 2+ . − Little attention has been paid to the IR fluorescence properties of TM 2+ -doped ZnSe nanocrystals.…”

Preparation, Structure, Optical and Morphological Properties of Co, Ga₂O₃ Co-Doped ZnS/Se

“…With the development of materials science and interdisciplinary convergence of disciplines, multi-doped gradually replaced single-doped as the mainstream doping mode due to its application diversity and abundant property of aggregation of each materials [10][11][12]. What's more, transition metal ions are widely used as an doped ions because of their excellent optical, electrical, and magnetic properties such as Co, Fe, Ni, Cu, Cr, Mn, Ni [13][14][15][16]. Co has abundant absorption and emission energy levels and ferromagnetism, which makes it attractive among other transition metals.…”
