Figure 4: TEM image of CNT-CdSe composite.

Mentions: Figure 3 shows the SEM microphotographs of CdSe and CNT-CdSe composite. From the Figure 3a, very uniform spherical-shaped CdSe particles with agglomerate together can be observed. For CNT-CdSe composite, as shown in Figure 3b, spherical-shaped agglomerated CdSe particles are mixed with MWCNTs. More detailed information of the surface state can be confirmed by the transmission electron microscopy (TEM). Figure 4 shows the TEM image of CNT-CdSe composite. It can be observed that the surface of MWCNTs have been coated with CdSe layers uniformly with particle size of about 10 nm.
