摘要
以β-环糊精为原料,采用一步热解法制备了发蓝光的石墨烯量子点;合成的石墨烯量子点厚度为1-2层的石墨烯,平均大小为27 nm,且发光具有激发波长的依赖性,加之石墨烯量子点发光稳定,无光漂白,低毒,具有良好的生物兼容性,使其在生物成像领域具有重要应用。
Blue luminescent graphene quantum dots( GQDs) were synthesized via a one-step pyrolytic route from beta-cyclodextrin. The obtained GQDs have single-layer and double-layer graphene sheets thick and an average diameter of 27 nm,and exhibit wavelength-dependent luminescence emission. In addition,GQDs have advantages including photoluminescence stability and resistance to photobleaching,low toxicity and excellent biocompatibility which could facilitate their applications in bioimaging field.
