Area of Science:

  • Materials Science
  • Nanotechnology
  • Photochemistry

Background:

  • Sulfur dots (SDs) are promising photoluminescent (PL) materials with good biocompatibility and photocatalytic activity.
  • Current SDs typically exhibit blue-to-green emission due to quantum confinement, limiting tunable visible light emission.
  • Achieving broad emission tunability in SDs is challenging due to the inherent band gap of bulk sulfur.

Purpose of the Study:

  • To develop white-light-emitting sulfur dots (SDs) through surface charge engineering.
  • To overcome the inherent limitations of sulfur's band gap for visible light emission.
  • To investigate the mechanism behind the white-light emission in engineered SDs.

Main Methods:

  • Surface hybridization of sulfur dots with oleylamine.
  • Photoluminescence spectroscopy to characterize emission properties.
  • Experimental and theoretical analysis to understand the emission mechanism.

Main Results:

  • Successfully achieved white-light emission from sulfur dots with broadband emissions (187 nm FWHM).
  • Obtained photoluminescence quantum yields up to 12.1% and CIE coordinates of (0.27, 0.32).
  • Identified strong orbital coupling between oleylamine and sulfur, leading to electron delocalization and low-energy charge transfer states.

Conclusions:

  • Surface charge engineering via oleylamine hybridization enables efficient white-light emission in SDs.
  • The generated charge transfer states are crucial for the multi-energy emissions responsible for white light.
  • This work represents a significant advancement in developing tunable, sulfur-based photoluminescent materials.
