The application discloses a room-temperature phosphorescent carbon
quantum dot material which can be
mass-synthesized and a preparation method thereof, and belongs to the technical field of luminescent
carbon dot materials.The preparation method comprises the following steps: taking a certain proportion of
pyromellitic dianhydride,
melamine and
boric acid,
grinding the materials in a
quartz mortar, placing the materials in a
corundum crucible, calcining the materials under the condition of 150-300 o C for 2-12 hours, cooling the materials to
room temperature after the reaction is completed,
grinding the materials into uniform
powder, and obtaining the final product.The room-temperature phosphorescent carbon
quantum dot is prepared by innovative
raw material allocation, the one-step high-temperature
solid-
phase method is adopted in the preparation process, the process flow is simple, the cost is low, and the room-temperature phosphorescent carbon
quantum dot material can be
mass-prepared and has excellent reproducibility.
