Optical Properties of Rhodamine B and Cadmium Telluride as Temperature Sensors


Rhodamine B dye and Cadmium Telluride quantum dots are non-invasive materials that have potential application as localized temperature sensors in microfluidic devices due to the temperature-dependent qualities of their photoluminescence (PL) lifetime lengths. In order to determine the specific nature of these relationships, PL spectral data and time-resolved PL data were collected in two temperature regimes between 10 K and 319 K and analyzed using methods including instrument response function deconvolution and machine learning. After extensive study, Rhodamine B’s use as a temperature sensor was deemed impractical due to other interfering factors, but Cadmium Telluride has shown promising results with temperature prediction accuracies of 3.4 K and 0.2 K for the low and high temperature regimes respectively.
