Area of Science:

  • Materials Science
  • Photonics
  • Analytical Chemistry

Background:

  • Controlling material emission properties is crucial for advanced optical sensing.
  • Existing methods often lack the dynamic range needed for sensitive quantitative detection.

Purpose of the Study:

  • To demonstrate a material exhibiting tunable emission lifetimes and intensity.
  • To develop a time-domain stepwise encoding method for enhanced quantitative detection.
  • To apply this method to point-of-care testing (POCT).

Main Methods:

  • Fabrication and characterization of a novel stepped photon emission material.
  • Implementation of a time-domain stepwise encoding strategy.
  • Validation of the method in a point-of-care testing scenario.

Main Results:

  • Achieved tunable emission lifetimes (sub-milliseconds and seconds) at a single wavelength.
  • Observed an abrupt intensity change between emission states.
  • Demonstrated an ultra-large quantitative detection range using the developed encoding method.

Conclusions:

  • The developed stepped photon emission material offers unique tunable optical properties.
  • The time-domain stepwise encoding method significantly expands quantitative detection capabilities.
  • This approach shows great promise for sensitive and wide-range point-of-care diagnostics.
