Study of the oxygen role in the photoluminescence of erbium doped nanocrystalli...
Cerqueira, M. F.; Losurdo, M.; Monteiro, T.; Stepikhova, M.; Soares, M. J.; Peres, M.; Alves, E.; Conde, O.We have produced and studied erbium doped nanocrystalline silicon thin films with different oxygen and hydrogen content in order to evaluate the influence of the matrix on the Er3+ emission and on the 0.89 eV and 1.17 eV bands. Films were grown by reactive magnetron sputtering on glass substrates under several different conditions (RF power, Er content and gas mixture composition) in order to obtain different m...

Cerqueira, M. F.; Losurdo, M.; Stepikhova, M.; Conde, O.; Giangregorio, M. M.; Pinto, Pedro; Ferreira, J. A.We have produced and studied undoped and erbium-doped nanocrystalline silicon thin films in order to evaluate the erbium influence on the film microstructure and how this correlates with the photoluminescence properties. Films were grown by reactive RF sputtering. For the doped films metallic erbium was added to the c-Si target. The structural parameters and the chemical composition of the different samples wer...
