NOVELTY - Preparing flexible supporting chlorine doped graphene quantum dot thin film comprises e.g. (i) mixing liquid paraffin and chloroform, preparing chlorine-doped carbon nano ball using co-combustion method, ultrasonicating and centrifuging to obtain doped graphene quantum dot, (ii) mixing basic component of organoelastic silicone of polydimethylsiloxane and curing agent, agitating, adding chlorine doped graphene quantum dot, and agitating, and (iii) mixing 10 pts. wt. basic component of the organoelastic silicone of polydimethylsiloxane and 1 pts. wt. curing agent, agitating with glass rod for 1 minute, then adding chlorine doped graphene quantum dot mixture, continuously stirring for 5 minutes with glass rod to mix, and (iv) respectively dropping step (ii) obtained mixture with mixture prepared in step (iii) into sample box by dripping tube, placing in a drying box and drying to obtain flexible supporting different chlorine concentration doped graphene quantum dot film. USE - The quantum dot thin film is useful for organic light-emitting diodes (OLED) photoelectric field. ADVANTAGE - The method has flexibility, transparency; the quantum dot thin film has enhanced light absorption; and is suitable for large-scale production.
