Nanoparticle thermometry and pressure sensors
First Claim
1. A nanoparticle fluorescence (or upconversion) sensor, comprising:
- an electromagnetic source emitting an excitation;
a sample positioned within the excitation emitted by the electromagnetic source; and
sensory material associated with at least a portion of the sample and receiving at least a portion of the excitation emitted by the electromagnetic source, the sensory material including a plurality of luminescent nanoparticles luminescing upon receipt of the excitation, with the luminance emitted by the luminescent nanoparticles changing based on at least one of temperature and pressure;
a detector receiving at least a portion of the luminance emitted by the luminescent nanoparticles and outputting a signal indicative of such luminance; and
means for correlating said signal into a measurement of the temperature or pressure adjacent to the sensory material.

Abstract
A nanoparticle fluorescence (or upconversion) sensor comprises an electromagnetic source, a sample and a detector. The electromagnetic source emits an excitation. The sample is positioned within the excitation. At least a portion of the sample is associated with a sensory material. The sensory material receives at least a portion of the excitation emitted by the electromagnetic source. The sensory material has a plurality of luminescent nanoparticles luminescing upon receipt of the excitation with luminance emitted by the luminescent nanoparticles changing based on at least one of temperature and pressure. The detector receives at least a portion of the luminance emitted by the luminescent nanoparticles and outputs a luminance signal indicative of such luminance. The luminescence signal is correlated into a signal indicative of the atmosphere adjacent to the sensory material.
