Temperature sensing behaviour of the stark sublevels.
The temperature dependence of the fluorescence intensity ratio of the two stark components of (4)S(3/2)-->(4)I(15/2) transition using 800 nm radiation from a Ti-sapphire laser pumped by the second harmonic of Nd:YVO(4) laser has been augmented in Er(3+) doped tellurite glass. It is emphasized that even the two stark components of (4)S(3/2)-->(4)I(15/2) transition may be utilized to monitor the temperature within 300-550 K with its appreciable sensitivity.
