Micro-laser Raman spectra of CuO particles synthesized by the X-ray irradiation of aqueous Cu(CH3COO)2 solution with different volumetric ratios of ethanol: (a) 3000:1, (b) 2000:1, (c) 200:1 and (d) 2:1. The corresponding ratios described in molar concentration are Cu(CH3COO)2:ethanol = (a) 0.37:5.72 × 10−3, (b) 0.37:8.17 × 10−3, (c) 0.37:8.17 × 10−2 and (d) 0.36 M:8.17 × 10−1M. The insets are optical micrographs of the particles; the position of the green light indicates the measurement position of the excitation laser (wavelength 532 nm).
