MgAl2O4:Cr3+ probe for luminescence thermometry in the physiological temperatures range
Апстракт
Temperature sensing from the photoluminescence of MgAl2O4:Cr3+ powder is systematically examined and presented. The material was prepared by the self-propagating high-temperature synthesis method and its structure was confirmed by X-ray diffraction analysis. In this host, Cr3+ ions are in a strong crystal field, so the overlapping emissions from 2E and 4T2 energy levels are observed. Emission and excitation spectra were recorded in the 300 - 540 K temperature range. The broad photoluminescence attributed to 4T2→4A2 transition increases in intensity with an increase in temperature on account of 2E→4A2 emission intensity until 460 K when both emissions start quenching. The emissions were separated by deconvolution at each temperature and used for the luminescence intensity ratio temperature readout method. The obtained relative sensitivity displayed high values in the physiological range, from 3.5 %K-1 at 300 K to 2.9 %K-1 at 330 K, above 2 %K-1 below 400 K, and above 1 %K-1 between 400 ...K and 540 K.
