Environment of Er doped in a-Si:H and its relation with photoluminescence spectra 久米田, 稔 森本, 章治 清水, 立生 Kumeda, Minoru 9766 30019773 30019773 Sekizawa, Yoshitaka 10385 Morimoto, Akiharu 132 60143880 60143880 60143880 Shimizu, Tatsuo 9767 30019715 The crystal-field potential at the Er3+ ion surrounded by six oxygen ions is expanded in terms of polynomials. After converting it into equivalent angular momentum operators, the Stark-splitting of the 4I15/2 ground state of the Er3+ ion is calculated. Influence of the change in the environment of the Er3+ ion on the shift of the energy levels is investigated and compared with the observed Er photoluminescence spectrum in a-Si:H. The scattering of the calculated energy levels by the structural fluctuation around the Er 3+ ion is also compared with the linewidth of the component photoluminescence lines. © 2006 Materials Research Society. 金沢大学設計製造技術研究所 / 金沢大学理工研究域電子情報学系 / 金沢大学工学部 conference paper Materials Research Society 2007-01-01 AM application/pdf 910Materials Research Society Symposium Proceedings 910 131 136 0272-9172 https://kanazawa-u.repo.nii.ac.jp/record/7697/files/TE-PR-KUMEDA-M-131.pdf https://doi.org/10.24517/00007684 http://hdl.handle.net/2297/6746 https://kanazawa-u.repo.nii.ac.jp/records/7697 eng
