Paper Abstract

A multi-ions co-doped probe had been developed for radiation-based high-temperature fiber-optic sensing. The heavily (Nd3+, Er3+ and Cr3+)-co-doped probe was fabricated on one end of an Y2O3-ZrO2 waveguide by powder growth technique on an LHPG system. The wavelength-dependent absorption and emission spectra were measured, favorable results were obtained. In high temperature tests, the probe survived 2300 degree(s)C and showed a short-term stability at oxidative high temperature environment. The thermal response time of the probe is about 3.3s. Compared with metal- or oxide-coated probe, the doped probe demonstrated higher chemical and high-temperature stabilities.
