2022年11月5日 · In this work, core CdTe, core-shell CdTe/CdSe and alloy CdTeSe QDs are synthesized by aqueous solvent. TEM visually shows the rod-shaped core-shell structure with a transverse to longitudinal ratio of 6.5 and the ellipsoidal alloy structure with different crystal planes competing for growth.

2003年10月3日 · The formation of nearly monodisperse CdTe nanocrystals dots (either zinc blende or wurtzite crystal structure), rods, and tetrapods in a noncoordinating solvent was studied. Several strong ligand effects were observed, and the ligand effects on the monomers were found to play a more important role than the ligand effects on the nanocrystals.

2023年1月5日 · Pristine and Ag-doped CdTe QDs (0.5–5%) were synthesized in an aqueous medium. Silver doping kinetically controls the crystal shape and size of CdTe QDs. The shape has tuned gradually from octahedron to cubic via increasing silver concentration in CdTe. Absorption and emission were red shifted in relation to silver doping concentrations.

2005年4月12日 · We report a general synthetic method for the formation of shape-controlled CdS, CdSe and CdTe nanocrystals and mixed-semiconductor heterostructures. The crystal growth kinetics can be manipulated by changing the injection rate of the chalcogen precursor, allowing the particle shape spherical or rodlike to be tuned without changing the ...

2022年1月22日 · In nutshell, the proposed novel strategy of tunable CdSe/CdTe core-shell QDs with excellent structure, size and shape, morphology, and optical properties is suitable for photovoltaic and energy storage applications.

2013年2月6日 · Various shapes of CdTe nanocrystals, such as nanodots, nanorods, multipods, and nanowires, could be obtained by changing the reaction conditions. Tuning the reactivity of both the cadmium and the tellurium precursors at the same time was found to be the main reason for the shape control of CdTe nanocrystals in this reaction system.

2023年2月1日 · In this research, Solar Cell Capacitance Simulator (SCAPS-1D) is applied to explore the impact of absorber layer thickness and carrier concentration in realizing ultrathin CdTe solar cell. It has been found that 500 nm thick absorber layer …

Several kinds of hydrophobic quantum dots (QDs) including CdSe, CdTe, CdSe/CdxZn1−xS, and CdTe/CdSe/ZnSe were fabricated via organic synthesis to observe morphology variation during shell coating. CdSe QDs prepared at a relatively high temperature revealed a hexagonal structure and rod morphology.

2024年2月5日 · Despite the deep interest of materials scientists in cadmium telluride (CdTe) crystal growth, there is no single source to which the researchers can turn towards for comprehensive knowledge of CdTe compound semiconductor synthesis protocols, physical properties and performance.

2011年4月15日 · Hexadecylamine (HDA) capped CdTe nanoparticles have been synthesized using a facile hybrid solution based/thermolysis route. This method involves the reaction by the addition of an aqueous suspension or solution of a cadmium salt (chloride, acetate, nitrate or carbonate) to a freshly prepared NaHTe solution.
