In recent years, CdSe quantum dots are one of the most preferred nanomaterials. Highly monodisperse zinc blend CdSe quantum dots were synthesized using hot injection method. The structure and optical properties of the samples were determined by UV-Vis, photoluminescence, XRD and TEM methods. As a result, the difference between 2S-1P absorption transitions did not change with particle size. However, the difference between 1S-2S and 1S-1P transitions were found to be inversely proportional to particle size. The FWHM value of the photoluminescence spectrum of the smallest sample has decreased to 25 mm and Stokes shifts were observed to be 0.06 eV.trinfo:eu-repo/semantics/closedAccessCdSequantum dothot injectionoptical absorptionphotoluminescencenanotechnologySemiconductor ClustersPhotodetectorsCdteArticle2412530WOS:000620701600003N/A
