Area of Science:

  • Materials Science
  • Optoelectronics
  • Glass Chemistry

Background:

  • Chalcogenide glasses, specifically As-Se and Ge-Se systems, exhibit well-documented photo-darkening and photo-bleaching effects, respectively.
  • These phenomena indicate a sensitivity to light-induced structural and optical property alterations.
  • Understanding the interplay of these effects is crucial for developing stable optical materials.

Purpose of the Study:

  • To systematically investigate the dependence of photo-induced optical changes on the germanium (Ge) to arsenic (As) ratio in Ge(x)As(45-x)Se(55) glasses.
  • To identify a specific Ge/As composition exhibiting intrinsic photo-stability.
  • To demonstrate the potential of this photo-stable glass for fabricating photo-insensitive optical components.

  • Synthesis of a series of Ge(x)As(45-x)Se(55) glasses with varying Ge/As ratios (x).
  • Characterization of photo-induced optical changes (e.g., refractive index, absorption) upon light exposure.
  • Analysis of the relationship between the Ge/As ratio and the observed photosensitivity.

Main Results:

  • A systematic trend in photo-induced optical changes was observed across the Ge(x)As(45-x)Se(55) glass series, transitioning between photo-darkening and photo-bleaching behaviors.
  • A specific composition, Ge(x)As(45-x)Se(55) with x approximately 10, demonstrated intrinsic photo-stability, exhibiting minimal photo-induced optical changes.
  • This finding validates the prediction that the Ge/As ratio governs the photosensitivity of these glasses.

Conclusions:

  • The Ge/As ratio is a critical parameter controlling the photosensitivity of Ge-xAsxSe(55) glasses.
  • The identification of an intrinsically photo-stable chalcogenide glass composition (x ≈ 10) opens new avenues for optical material development.
  • This photo-stable glass is suitable for fabricating robust, photo-insensitive optical components for diverse technological applications.
