Figure 2

a–c TEM Images and SAED pattern of CdSe nanocrystals synthesized at room temperature:a the homocentric ring;b the oval and irregular rings (inset is the SAED pattern of the ring in the imageb);c the tribulus-shaped nanoparticles (inset is a natural tribulus);d and e TEM images of CdSe nanorings prepared at 60 °C and 100 °C, respectively;f Room temperature photoluminescence spectra of products obtained at (I) room temperature, (II) 60 °C, and (III) 100 °C (Excitation wavelength: 450 nm)
