| 摘 要： | The green and red up-conversion emissions centred at about 534, 549 and 663 nm of wavelength, corresponding respectively to the ^2H11/2 → ^4I15/2, ^4S3/2 → ^4I15/2 and ^4F9/2 → ^4I15/2 transitions of Er^3＋ ions, have been observed for the Er^3＋-doped silicate glass excited by a 978 nm semiconductor laser beam. Excitation power dependent behaviour of the up-conversion emission intensity indicates that a two-photon absorption up-conversion process is responsible for the green and red up-conversion emissions. The temperature dependence of the green up-conversion emissions is also studied in a temperature range of 296-673 K, which shows that Er^3＋-doped silicate glass can be used as a sensor in high-temperature measurement.

| Abstract: | The green and red up-conversion emissions centred at about 534, 549and 663,nm of wavelength, corresponding respectively to the${^{2}}H_{11 / 2} to {^{4}}I_{15 / 2}$, ${^{4}}S_{3 / 2} to{^{4}}I_{15 / 2}$ and ${^{4}}F_{9 / 2} to {^{4}}I_{15 / 2}$transitions of Er$^{3 + }$ ions, have been observed for the Er$^{3 +}$-doped silicate glass excited by a 978,nm semiconductor laserbeam. Excitation power dependent behaviour of the up-conversionemission intensity indicates that a two-photon absorptionup-conversion process is responsible for the green and redup-conversion emissions. The temperature dependence of the greenup-conversion emissions is also studied in a temperature range of296--673,K, which shows that Er$^{3 + }$-doped silicate glass canbe used as a sensor in high-temperature measurement. |
