Cadmium selenide may also be produced in the form of nanoparticles. (see applications for explanation) Several methods for the production of CdSe nanoparticles have been developed: arrested precipitation in solution, synthesis in structured media, high temperature pyrolysis, sonochemical, and radiolytic methods are just a few. [9] [10]
In addition to gold and silver, Fusarium oxysporum has been used to synthesize zirconia, titanium, cadmium sulfide and cadmium selenide nanosize particles. Cadmium sulfide nanoparticles have also been synthesized by Trametes versicolor, Schizosaccharomyces pombe, and Candida glabrata. [18]
It is a linear molecule with C-Cd bond lengths of 213 pm. [1] The compound finds limited use as a reagent in organic synthesis and in metalorganic chemical vapor deposition (MOCVD). It has also been used in the synthesis of cadmium selenide nanoparticles, although efforts have been made to replace it in this capacity due to its toxicity. [2]
Dots may also be made from ternary compounds such as cadmium selenide sulfide. Further, recent advances have been made which allow for synthesis of colloidal perovskite quantum dots. [28] These quantum dots can contain as few as 100 to 100,000 atoms within the quantum dot volume, with a diameter of approximately 10 to 50 atom diameters.
When the cadmium reagent is generated in situ from a cadmium salt, the halide generates a more nucleophilic organocadmium reagent, an ate complex. The same salt effect can be observed with organozinc compounds. Dimethylcadmium has been used to synthesize colloidal nanocrystals of II-VI materials such as cadmium selenide. Its toxic and volatile ...
Sample of cadmium selenide, a pigment. The parent inorganic selenide is hydrogen selenide (H 2 Se). It is a colorless, malodorous, toxic gas. It dissolves in aqueous solution, to give the hydrogenselenide or biselenide ion HSe −. At higher pH, selenide forms. Solutions of hydrogen selenide and selenide are oxidized by air to give elemental ...
As you can see, there’s nothing special about the list, and any way you set it up can work. The point is to create the number of categories that make it easy to know where you stand financially ...
Aerogels made of cadmium selenide quantum dots in a porous 3-D network have been developed for use in the semiconductor industry. [73] Aerogel performance may be augmented for a specific application by the addition of dopants, reinforcing structures, and hybridizing compounds. For example, Spaceloft is a composite of aerogel with some kind of ...
