Raman, FTIR and PL spectra of the (Zn,H)-codoped copper oxide nanocondensates. (a) Raman, (b) FTIR, and (c) PL spectra of the (Zn,H)-codoped copper oxide nanocondensates prepared by PLA in water (top black trace) followed by dwelling in water for 1 (middle red trace) and 20 days (lower blue trace). The FTIR bands at 2,850 and 2,920 cm−1 are due to EtOH contamination during IR sample preparation.
