Is CdSe stable?

Furthermore, we find that type I CdSe/CdS/ZnS QDs are fairly stable during the thermal annealing process of a QD–SiO2/Al2O3 monolith (SAM) phosphor, but quasi-type II CdSe/CdS QDs easily lose their emission possibly because the delocalized electrons to the shell are more susceptible to being captured by the surface …

Which property of CdSe is critical for optical applications?

The color of the light depends on the size of the quantum dots. The results showed that, CdSe quantum dots with sizes ranging from 2.27 nm to 3.75 nm, enabled the control of the optical properties.

What is CdSe in chemistry?

Cadmium selenide | CdSe – PubChem.

How do you make cadmium selenide?

Procedure

  1. Add 13 mg of CdO to a 25 mL round bottom flask clamped in a heating mantle.
  2. To the same flask, add by pipet 0.6 mL oleic acid and 10 mL octadecene.
  3. Heat the cadmium solution.
  4. Remove approximately 1 mL samples at frequent intervals using a 9 inch glass Pasteur pipet as the CdSe particles grow in size.
