General description

Gallium(III) acetylacetonate is a white to off-white crystalline solid with purity (99.99% trace metals basis) widely used as a precursor for thin films and nanomaterials. It is soluble in organic solvents such as ethanol, acetone, and toluene, making it suitable for solution-based nanoparticle synthesis. Its thermal stability, with decomposition occurring above ~200 °C, allows for controlled gallium release, making it ideal for the synthesis of nanomaterials and oxide layers. It is commonly employed in metal-organic chemical vapor deposition (CVD) and atomic layer deposition (ALD) to produce gallium oxide (Ga₂O₃) and gallium nitride (GaN) thin films, which are essential for electronic and optoelectronic applications.

Application

Gallium(III) acetylacetonate can be used:
  • As a precursor to synthesize nanocrystalline gallium oxide spinels via solvothermal process for various applications like photocatalysis, battery cathode materials and electrocatalysis.
  • To fabricate LiGa alloy layer on Li metal anode from in-situ electroreduction. It suppresses the anode dendrite formation in lithium-sulfur batteries.
  • To prepare highly efficient gallium-platinum (GaPt3) nanoparticles hot-solvent synthesis which act as electrocatalysts for hydrogen evolution reaction.
  • To synthesize γ-Ga2O3 nanocrystals for fabricating electron-transporting layer for perovskite solar cells. It forms effective interfacial connections with the perovskite top layer, enhancing the efficiency of charge transport.

Features and Benefits

  • The high purity (99.99% trace metals basis) ensures that no impurities interfere with the synthesis process, leading to higher yields and better quality of the gallium compounds.
  • High purity enhances catalytic activity and selectivity, reducing the formation of by-products and improving overall reaction efficiency.
  • The absence of trace metal impurities ensures the integrity and performance of the thin films, resulting in improved device efficiency and longevity of optoelectronic devices.
  • The high purity of the precursor minimizes defects and impurities in the semiconductor materials, enhancing their electrical properties and performance.
