    Area of Science:

    • Materials Science
    • Nanotechnology
    • Optoelectronics

    Background:

    • Germanium dioxide (GeO2) nanowires are explored for optical applications.
    • Controlling nanowire morphology is crucial for waveguiding applications.
    • Doping can modify material properties for enhanced functionality.

    Purpose of the Study:

    • To synthesize and characterize tin (Sn)-doped GeO2 nanowires and microwires.
    • To investigate the effect of Sn doping on the morphology and optical properties of GeO2 wires.
    • To evaluate the waveguiding capabilities of Sn-doped GeO2 nanowires.

    Main Methods:

    • Evaporation-deposition method using Ge and SnO2 powder mixture.
    • Morphological analysis of doped and undoped GeO2 nanowires.
    • Optical characterization, including luminescence spectra and waveguiding tests.

    Main Results:

    • Sn doping prevented sharp bends in GeO2 nanowires, improving suitability for waveguiding.
    • Incorporation of ~0.5 at.% Sn led to wires with varying cross-sectional dimensions.
    • Sn doping did not affect visible luminescence but introduced near-infrared emission bands.
    • Waveguiding of green and red laser light was demonstrated in Sn-doped GeO2 wires.

    Conclusions:

    • Sn-doped GeO2 nanowires offer enhanced structural integrity for waveguiding.
    • The doping-induced morphological and optical changes are beneficial for optical device development.
    • These findings highlight the potential of Sn-doped GeO2 nanowires in optoelectronic and photonic applications.
