Zinc‐blende‐type cubic InSe and β‐In 2 Se 3 crystallites were synthesized using the solvo‐thermal method in this study. The crystalline structure, electronic and optical characterization of indium selenide particles were investigated using transmission electron microscopy ( TEM ), X‐ray diffractometer ( XRD ), UV–visible absorbance spectra. It was observed that the dominant crystalline structure of samples synthesized at 180°C for 1.5–48 h is zinc‐blende‐type cubic InSe phase with lattice parameter of about 0.573 nm. As the reaction temperature was raised to 200°C, the zinc‐blende‐type cubic InSe phase diminished and the β‐In 2 Se 3 phase was produced. The zinc‐blende‐type cubic InSe phase band gap is about 1.68 eV. These synthesized compounds provide promising candidates for solar cell applications.
