摘要

High-performance temperature sensors for the harsh environment are vital components for meeting the increasing demands for the development of existing and emerging technologies. In this study, specifically oriented (Mg1-xZnx)(Al1-yCry)(2)O-4 single-crystal fibers (SCF) are grown by the laser-heated pedestal growth technique and used as acoustic waveguides for ultrasonic temperature sensors (UTS) for the first time. The anisotropic sensor performance of the MgAl2O4 SCF-UTS are investigated under a longitudinal wave and transverse wave conditions, and the [110]-oriented MgAl2O4 SCF-UTS is found to have the highest sensitivity and resolution among all the MgAl2O4 SCF-UTS. On this basis, a unit sensitivity of 40.38-67.50 ns degrees C-1 m(-1) and a resolution of 1.24-0.74 degrees C are achieved for the [110]-oriented (Mg0.9Zn0.1)(Al0.995Cr0.005)(2)O-4 SCF-UTS in the range of 20-1200 degrees C, both of which represent the best sensor performance achieved by a SCF-UTS to date. The positive temperature-dependent sensor performance, accompanied by a high working temperature (approximate to 2000 degrees C) and outstanding anti-oxidation, indicates that the [110]-oriented (Mg0.9Zn0.1)(Al0.995Cr0.005)(2)O-4 SCF-UTS is a promising candidate for ultra-high temperature sensors. This study demonstrates a feasible strategy for the rational design of high-performance temperature sensors through a combination of crystal design, acoustic anisotropy, and lattice doping engineering.
