| titleOfInvention | Method for preparing purple fluorescence reduced oxidized graphene quantum dot |
| abstract | The invention discloses a method for preparing purple fluorescence reduced oxidized graphene quantum dot. According to the method, oxidized graphene, which is used as a raw material, is subjected to oxidation treatment by the use of nitric acid and sulfuric acid; an oxidized graphene solution which has been oxidized is subjected to ultrasonic decomposition by the use of a 200W ultrasonic machine for 14 hours; the solution is subjected to deacidification and cleaning by a centrifugal separation process at the rotating speed of 14000 r/m until pH value of the solution is adjusted to 8; high-pressure digestion is conducted at 200 DEG C for 12 hours; the solution which has undergone digestion is subjected to continuous dialysis by the use of a 8000-14000Da dialysis bag for about one week; the solution is dried in vacuum at 90 DEG C so as to obtain oxidized graphene quantum dot; the oxidized graphene quantum dot is reduced in the H2 atmosphere at 300-900 DEG C for 1 hour; and hydrogen is turned off, argon is introduced immediately, and a tubular furnace is naturally cooled to room temperature so as to obtain the reduced oxidized graphene quantum dot. According to the invention, any impure impurity materials are not added such that the prepared product has high purity; particle size distribution is uniform; and fluorescence can be adjusted from blue light to purple light. |
