摘要: The efficient excitation of Er3+ ions through contact with Si nanoparticles (NPs) is demonstrated. A nanostructured doping process has been developed that leads to between NPs formed in situ and optically-active embedded Al2O3. This achieved by independent consecutive deposition the dopants matrix. NP–Er3+ regime enhances probability interaction due local spatial overlap electronic states NP exciton, enabling energy transfer interband exciton recombination. up 53% being excited as-deposited films.
