Fig. 5From: Multiple ratiometric nanothermometry using semiconductor BiFeO3 nanowires and quantitative validation of thermal sensitivitya Luminescence intensity ratio (LIR) values of BFO nanowires as a function of temperature (circles). LIR values were obtained as the ratio between peak intensities for E1, E3, and E4 with respect to E2. b Relative and absolute sensor sensitivity obtained from LIR measurements as a function of temperature (300–438 K)Back to article page
