Abstract

The optical, morphological, structural, and photocatalytic properties of CdSe quantum dots are investigated in this research. The Solvo-thermal approach is used to make CdSe quantum dots, which is done at 60oC for 5 hours. The reducing agent hydrazine hydrate is used to prepare the CdSe nanoparticles. While using CdSe quantum dots as a photocatalyst, it was discovered that there were variations in the period of time needed to break down the dye. The dye degradation effect was characterized using a UV-Vis spectrophotometer. Using a Tauc plot formula, the band gap was determined to be 2.47 eV. The particle size has been determined by transmission electron microscopy to be 11.57 nm. The SAED pattern analysis supports the CdSe quantum dots crystalline structure. Using the Debye-Scherr formula, the XRD technique determines the crystallite size as 8.06 nm.
