Abstract:

C60 nanoparticles(C60NPs) were prepared through a modified ultrasonic process. The effects of ultrasonic bath temperature on the particle size and distribution of C60NPs, as well as the photoluminescence spectroscopy(PL) property of C60NPs were studied. The results show that as the ultrasonic bath temperature increase, the average particle size of C60NPs decrease and the dispersibility of C60NPs improve obviously. Thermogravimetric analysis(TGA) and infrared(IR) spectroscopy measurements indicate that water and solvent accounte for 57% of the total mass of C60NPs. After heating at 200 ℃, the particle size of C60NPs is significantly reduced, and subsequently the water soluble C60 quantum dots without solvent are obtained. The PL intensity from such water soluble C60 quantum dots is about one order of magnitude higher than that from the as-prepared C60NPs.
