How can I find the refractive index of Colloidal QDs (CdSe 6-10nm ) thin layer(20-30 nm)? I want to simulate QDs in a cavity. It would be great if someone can suggest me any reference.
For refractive index data, you can use the data for CdSe (irrespective of thickness or shape). Either the structure can be a nanowire or film or QD is not an issue. The database suggested by Mohammad will work fine for simulations.
