| 英文摘要 | the main goal of this work is to conjugate two independent techniques of tem-edx and optical spectroscopy, which is rare, for the localization of yb3+ and er3+ rare earth ions and co2+ transition metal ions as dopants in a compact self-q-switched microchip laser glass ceramic composed of mgal2o4 spinel nano-crystals of 10-20 nm size embedded in sio2 glass. the use of the tem-edx technique associated with both the elemental mapping of each dopant and the direct visualization of the heavier rare earth ions has led to the result that er3+ and yb3+ rare earth ions are preferentially located in the spinel nano-crystals. regarding the low co2+ concentration this technique was not accurate enough for characterization and finally we have used absorption spectroscopy to probe the main presence of co2+ ions in the spinel nano-crystals. the use of yb3+ ions as structural probes allows the identification of the 0-phonon broad line at 977 nm as both that of the disordered glass and that of the spinel inverted phases. a new yb3+ radiationless center has been pointed out by the presence of a strong absorption line at 970 nm which has been assigned to the strongly perturbed area of the spinel nano-crystallite surface. this dopant characterization is worthwhile to be shown as a special case where characterization of rare earth and transition metal ions needs the use of both tem and spectroscopic techniques. |
