Abstract

The influence of temperature on the spectral composition and luminescence intensity of oxyfluoride glasses containing molecular clusters of silver and ions of the rare-earth metals samarium and terbium has been investigated. It is shown that introducing these ions into the composition of the glass increases the luminescence intensity of the molecular clusters of silver and the temperature sensitivity of their luminescence intensity. In oxyfluoride glass with molecular clusters of silver and Tb<sup>3+</sup> ions, the overall luminescence intensity in the 20°C–250°C temperature range is attenuated by a factor of 50. It is shown that molecular clusters of silver are characterized by temperature sensitivity of the luminescence intensity in the range 0.045–0.099  dB/°C.
