Indium Corp to supply high-quality gallium acetylacetonate

Indium Corp of Clinton, NY, USA is to supply high-purity gallium acetylacetonate ( Ga(acac)3), an organometallic coordination complex with gallium at the center surrounded by three acetylacetonate ligands that, due to its versatility and stability, has several applications in materials science, organic chemistry and catalysis.

Through heating and decomposition, the Ga(acac)3 can be used to produce a highly pure and uniform thin-film version of gallium oxide (Ga2O3). This unique variation of Ga2O3 finds common use as an ultrawide-bandgap (~4.8eV) semiconductor in power electronics applications.

Indium Corp says that its Ga(acac)3 can be combined with sulfur to synthesize gallium sulfide (Ga2S3) quantum dots with an approximate bandgap of 3.30eV. The resulting Ga2S3 quantum dots are well suited for use in photonics and optoelectronics. Ga(acac)3 can also be used to prepare quantum dots of gallium arsenide (GaAs), gallium phosphide (GaP), and gallium indium phosphide (GaInP), with potential applications in quantum photonics.

Additionally, Ga(acac)3 serves as a thermally stable replacement for trimethyl gallium (TMG) in high-temperature deposition processes. It decomposes at higher temperatures and is not pyrophoric like TMG, making it safer to handle. The crystalline powder form of Ga(acac)3 adds to its ease of handling compared with the liquid state of TMG.

Indium Corp notes that, with purity starting at 99.99%, it can optimize its Ga(acac)3 to the specific needs of its customers.
