Graphene quantum dots (GQDs) have garnered immense interest in recent years due to their unique optical, electrical, and chemical properties, making them promising candidates for various applications optoelectronics, bioimaging, sensing. However, enhancing the control over size, surface chemistry, optical properties of GQDs remains a significant challenge. In this study, novel recipe was proposed successfully synthesize via typical solvothermal process, which has proven be versatile scalable approach. addition main ingredient – graphene oxide suspension, dimethylformamide (DMF) hydrogen peroxide serving as cutting agent were added reaction mixture. This synthesis method found more than reference one DMF replaced by double distilled water. Through systematic experimentation, we demonstrated that enables successful GQD production wider range times; hence, UV absorption band photoluminescence can better adjusted. The dependence on excitation wavelength observed as-prepared materials they excited with wavelengths from 360 480 nm. obtained insights not only advance our understanding but also open up avenues tailoring specific applications.
