Abstract: | CdS nanoarrays with the particles' diameter of about 1 nm were assembled in the nanochannels of the host of VSB-5 nanorods. Obvious UV–vis absorption peaks with the onsets of about 350–400 nm were clearly observed. Compared with the band-gap absorption at about 515 nm of the large CdS particles at room temperature, about 115–165 nm of the blue-shifts occurred for the nanoarrays due to the quantum confinement effect. |
