| Resumo |
We have investigated the temperature and pressure dependences of the copper-related green emission, which show fine structure at low temperature, from tetrapodlike ZnO microrods. The temperature dependence of the green emission energy follows the changes in the band gap from 10-200 K, but deviates from this behavior above 200 K. The pressure dependence of the copper-related green band (25 +/- 5 meV/GPa) is similar to that of the band gap of ZnO, and is larger than that reported previously for defect-related green emission in ZnO.
