The article describes the preparation and testing of optical properties of carbon quantum dots. optical properties were tested using a UV-VIS spectrophotometer and spectrometer. The maximum absorbance was determined in the range of  ~377 to ~408nm. All solutions obtained showed an emission corresponding to the wavelength in the green light range. Furthermore, the effect of solution concentration on the optical properties of carbon quantum dots was investigated.
