| 内容記述 | Abstract Erbium doped chalcogenide glasses (((Ge30(Se+S)70)100-xGax)100-y:Ery (x=3, 6, 9 and 12, y=0.3～3.0 at.%) were prepared by melt quenching methods. We observed the absorption coefficient of Er3+ ions at 976nm and 1540nm, and the intensity of 1550 nm band photoluminescence (PL), which was excited by a 976nm laser. Raman scattering spectra were also observed. These results were obtained as a function of Ga and Er contents. The absorption spectra shapes of Er3+ ions didn't change with Ga and Er contents. The absorption coefficients proportionally increased with increasing Er contents, and were saturated at the ratio of atomic % in which Er/Ga ratio equal to 1/5 except for x=12 samples. We found that the PL intensity increased with increasing Er contents, then reached a maximum at about the same atomic ratio. In the Raman spectra, the structure of glasses changed with Ga contents. These results imply that Er3+ ions and Ga atoms form domains which included high ionicity bonds with Er3+ in the matrix. The structure would be influenced the solubility of Er3+ ions in the host glass. |
