“…Walker et al first characterized the temperature response of the photo-luminescence (PL) of colloidal QDs immobilized inside a polylaurylmethacrylate (PLMA) matrix [10] proving the suitability of QDs as temperature references for PL-based sensing applications. Other authors have also reported the use of different host polymers such as polystyrene (PS) [11] or polymethylmethacrylate (PMMA) [12] to embed QDs, and even coupling the light with the aid of optical fibers [13]. All these works use the PL of QDs as the sensing parameter, but none of them integrate the PL response into an optical waveguide, which is the key step to develop a temperature sensor into a photonic device.…”

“…We have recently demonstrated that QD luminescence can be used to provide a self-referenced, intensity based, temperature measurement. 23 The temperature information is obtained by measurement of the shift in the peak wavelength. The luminescent intensity of the QDs also changes in a linear fashion with temperature.…”
