High intense blue-violet luminescent carbon dots derived from camphor soot
Highly luminescent carbon quantum dot with Blue-Violet emission was synthesized from camphor by simple combustion followed by sonication. Prepared carbon dots were characterized by transmission electron microscopy, uv absorption spectroscopy, Fourier transform infrared spectroscopy and photoluminescence spectroscopy. The synthesized carbon dots have very small size of less than 10nm. Fluorescence study of the prepared carbon dots revealed that it has an excitation independent emission in the near-uv wavelengths with a fluorescence red shift from 385nm to 430 nm by ageing.Highly luminescent carbon quantum dot with Blue-Violet emission was synthesized from camphor by simple combustion followed by sonication.
