1. A method of preparing a liquid indium selenide precursor, the method comprising:

  • reducing elemental selenium with a stoichiometric amount of hydrazine in the presence of a first solvent to yield a first solution comprising Se22−

    ; and

    combining the first solution with a second solution comprising an indium salt and a second solvent to yield the liquid indium selenide precursor comprising a suspension of indium selenide particles,wherein the liquid indium selenide precursor is substantially hydrazine-free.
