One-Step Synthesis of Copper and Cupric Oxide Particles from the Liquid Phase by X-Ray Radiolysis Using Synchrotron Radiation

Figure 6

(a) Micro-Raman spectrum of the particle attached on the core particle. The optical image of a typical aggregate is shown in the inset of (b). The green portion of the inset photograph shown in (B) shows the position irradiated by the green laser (wavelength = 532 nm). Micro-Raman spectra of (b) the Si substrate, (c) core and particle attached on the core particle, and (d) other particles, respectively. Indexes were taken from the following Raman spectrum patterns: Cu₂O, CuO, and Cu₄O₃ [38, 39].
