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

Figure 15

Micro-Raman spectrum of the particle aggregate synthesized from CuSO₄ solution mixed with ethylene glycol (solution #5). The inset photographs display the green laser position on the measurement area. Indexes were taken from the following Raman spectrum patterns: Cu₂O, CuO, and Cu₄O₃ [38, 39].
