Micro-laser Raman spectra of the particles synthesized by the X-ray irradiation of aqueous Cu(COOCH3)2 solution with the additive (a) methanol (R-1), (b) ethanol (R-2), (c) 2-propanol (R-2′) and (d) 1-propanol (R-3). 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). |
