Intermediate excited state suppression and upconversion enhancement of Er3+ ions by carbon-doping boosting photocarrier separation in bismuth oxychloride nanosheets

The spontaneous IEF inside the BiOCl was improved significantly by C doping, which can suppress the recombination of photoelectron-hole pairs. The stronger IEF inhibits the recombination rate of electrons on the intermediate state 4I13/2 of Er3+ ions, which promotes the energy reabsorption transitio...
