Area of Science:

  • Materials Science
  • Nanotechnology
  • Photonics

Background:

  • Lanthanide-based coordination polymers (CPs) offer tunable structures and luminescence.
  • Limited stability and morphology control hinder their use in photonic applications.

Purpose of the Study:

  • Synthesize stable Europium-based CPs with controlled microrod morphology.
  • Investigate their potential as optical waveguides for communication.

Main Methods:

  • In situ structure transformation of a precursor (compound 1) to form Europium-based CPs (compound 2).
  • Characterization of morphology, stability, and photoluminescence properties.
  • Measurement of optical loss coefficient for waveguide performance.

Main Results:

  • Successfully synthesized highly regular 1D microrod morphology of Europium-based CPs.
  • Achieved excellent material stability and high photoluminescence quantum yield (PLQY).
  • Demonstrated low optical-loss coefficient (0.00894 dB μm⁻¹) characteristic of photoactive waveguides.

Conclusions:

  • Developed stable, luminescent Europium-based CP microrods.
  • Extended the application of lanthanide-based CPs in optical waveguides.
  • Showcased potential for use in optical communication systems.
