Area of Science:

  • Materials Science
  • Photonics
  • Nanotechnology

Background:

  • Two-dimensional (2D) MXenes possess unique layered structures and high surface area, enabling diverse applications.
  • While MXenes show nonlinear optical properties, their second-harmonic generation (SHG) behavior remains largely unexplored.
  • Understanding SHG in MXenes is crucial for advancing their photonic and optical applications.

Purpose of the Study:

  • To demonstrate and quantify the second-order nonlinear optical responses of 2D Ti3C2Tx MXenes.
  • To investigate the SHG properties in both aqueous solutions and on solid substrates.
  • To explore the potential of MXenes in sensing and surface catalysis applications.

Main Methods:

  • Utilized second-harmonic scattering (SHS) to detect and quantify SHG signals.
  • Employed angle-dependent SHS experiments to elucidate the origin of the second-order responses.
  • Applied confocal and atomic force microscopy to study the relationship between MXene thickness and SHG intensity.
  • Investigated dye molecule adsorption (crystal violet and malachite green) on MXene surfaces via SHS.

Main Results:

  • Demonstrated significant SHG in 2D Ti3C2Tx MXenes, with high sensitivity (<0.1 μg/mL) in dilute suspensions.
  • Confirmed coherent 2D dipole radiation as the source of the second-order responses.
  • Observed an exponential increase in SHG with decreasing MXene thickness, contrasting with linear two-photon fluorescence.
  • Determined a second-order susceptibility of 3.6 pm V⁻¹ for 10 nm thick MXenes, surpassing beta barium borate.
  • Showcased distinct adsorption behaviors of crystal violet and malachite green on MXene surfaces, indicating potential for selective sensing.

Conclusions:

  • 2D Ti3C2Tx MXenes possess substantial second-order nonlinear optical properties, particularly SHG.
  • The thickness-dependent SHG and distinct dye adsorption behaviors highlight MXenes' potential in advanced photonic and sensing applications.
  • This research paves the way for novel applications of MXenes in photonics, optics, and surface catalysis.
