Interplay between Solubility Limit, Structure, and Optical Properties of Tungsten-Doped GaO Compounds Synthesized by a Two-Step Calcination Process.

This work unfolds the fundamental mechanisms and demonstrates the tunable optical properties derived via chemical composition tailoring in tungsten (W)-doped gallium oxide (GaO) compounds. On the basis of the detailed investigation, the solubility limits of tungsten (W) ion and associated effects on the crystal structure, morphology, and optical properties of W-doped GaO (GaW O, 0.00 ≤ x ≤ 0.
