Area of Science:

  • Materials Science
  • Nanotechnology
  • Optoelectronics

Background:

  • Achieving multicolor emission and dynamic color tuning over a broad spectral range is crucial for applications like lighting, displays, and communication.
  • Existing methods often face challenges in realizing continuous color tuning and large spectral coverage.

Purpose of the Study:

  • To report excitation-power-dependent color-tuning emission from individual Sn-doped CdS nanowires.
  • To demonstrate continuous color tuning across a large spectral range using a single nanostructure.

Main Methods:

  • Fabrication of Sn-doped CdS nanowires with a specific CdS to SnO2 weight ratio (10:1).
  • Characterization of photoluminescence (PL) spectra.
  • Modulation of excitation power to observe emission color changes.

Main Results:

  • Demonstrated excitation-power-dependent photoluminescence in Sn-doped CdS nanowires.
  • Observed a broad trap-state emission band superimposed with whispering-gallery (WG) microcavity effects and CdS band-edge emission.
  • Achieved continuous color tuning from red to green by varying excitation power from 0.25 to 1.36 mW.

Conclusions:

  • Sn-doped CdS nanowires exhibit stable properties and a large spectral range for emission color tuning.
  • These nanowires are promising candidates for nanoscale optoelectronic devices requiring dynamic color control.
