Green and high yield synthesis of CdTe@Hydrotalcite nanocrystals with enhanced photoluminescence stability toward white light emitting diodes

Microfluidic fluorescent platform for rapid and visual detection of veterinary drugs

“…2a-c can be seen in high-resolution TEM (HRTEM) observations (inset in Fig. 2a-c), and the lattice stripe with a planar spacing of 0.21 nm matches the (111) plane of CdTe QDs, 27,32 conrming the good crystallinity of these CdTe QDs. The sizes of the three CdTe QDs are distributed in the regions of 3-6 nm, 3-5 nm and 3-7 nm, with average diameters of 4.2 nm, 5.1 nm and 3.7 nm, respectively (Fig.…”

“…NaHTe was prepared according to a method described previously in the literature, 27 with some modifications. Briefly, 0.5 mmol of Te powder and 3.0 mmol of NaBH 4 (1 : 6 molar ratio of Te to NaBH 4 ) were loaded into a 5 mL strain flask and 2 mL of pure water was added.…”

“…The synthesis of CdTe QDs was performed according to a previously reported procedure. 27 In a typical synthesis, 1 mmol CdCl 2 ·2.5H 2 O was weighed into a 100 mL three-necked flask with a condenser and 40 mL of pure water was added to dissolve it. Then 5 mL of aqueous solution containing organic ligand (2.5 mmol MPA or 0.5 mmol TGA or 1.5 mmol NAC) was injected under vigorous stirring.…”

Hybridization of layered double hydroxides with functional particles

“…The incorporation of various QDs into pre-synthesized LDHs was examined. [175][176][177][178][179][180][181]…”

Enhancement in microstructural and optical properties of thermally evaporated CdTe/CdSe heterojunction thin Films

“…Cadmium telluride (CdTe) is II-VI crystalline compound with a zinc blende crystal structure and has a direct bandgap of 1.44 eV, which is suitable for electronic applications such as photovoltaic devices, light-emitting diodes, solar cells, X-ray and gamma detectors, Field Effect Transistors (FETS), Lasers and non-linear integrated optical devices [21,5,13,7,9,11,14,18,27,3]. CdTe is the only II-VI compound that can be prepared with a high conductivity in both n and p type forms [8].…”
