Paper Abstract

In the article effect of temperature on luminescent properties of antimony - silicate glass co - doped with 1.0mol%Yb3+/1mol%0.2Tm3+ under 976 nm was investigated. As a result of optical excitation with radiation with the wavelength of 976 nm three luminescence bands were obtained: 477 nm for 1G43H6 quantum transition, 650 nm for 1G43F4 and 698 nm for 3F2,3→3H6 in thulium ions, formed by the efficient Yb3+ → Tm3+ energy transfer. It has been found that the increase in temperature of a glass leads to higher probability of phonon transitions from the 1G4 to the 3F2,3 level leading to quenching of luminescence band with the wavelength within the band of 650 nm. The maximum sensitivity to temperature change is 0.02139 [K-1] at 250°C. The nature of a change over a range of studied temperature from 5 to 250°C is linear. The results of the research indicate that the fabricated glass can be used to construct luminescence temperature sensors.
