Abstract
Recent discoveries of pressure dependence in quantum dot (QD) fluorescence wavelength has led to work pursuing QD-based systems for strain and pressure-sensing applications. However, the spectral shift of QDs tends to be fairly insensitive, typically requiring applied pressure on the order of gigapascals before any change can be detected. We present a QD-epoxy nanocomposite whose spectral intensity response to pressure can be used to quantitatively detect pressure changes in the megapascal range. The intensity of QD fluorescence is compared to the intensity of a reference to provide meaningful intensity data, which provides a bright signal that is quantitatively indicative of material stress. We believe that further optimization and characterization of this nanocomposite may be useful in the development of sensitive optical strain sensors.
