镓（Ga）

Gallium acetylacetonate (Ga(acac)₃) is an organic compound. Technically, it represents an organometallic coordination complex with gallium at the center, surrounded by three acetylacetonate ligands. When heated in the presence of oxygen, gallium acetylacetonate decomposes into gallium oxide (Ga₂O₃). This property makes Ga(acac)₃ a useful precursor for growing highly pure and uniform Ga₂O₃ thin films on substrates such as glass and silicon. Ga(acac)₃ is used in the production of quantum dots like Ga₂S₃, GaAs, GaP, and GaInP.
