摘要： The present invention relates to a process for the preparation of blue-fluorescence emitting carbon dots (CDTs) from sub-bituminous tertiary high sulfur Indian coals. More particularly, the present invention relates to the production of characteristics carbon dots from low-quality Indian coals by an ultrasonic-assisted wet-chemical method. Also, the present invention provides a simple and environmentally benign method for fabrication of characteristics and size-controlled carbon dots.
