In2Se3 nanoparticles, flower-like shaped and sheet-shaped nanocrystals were synthesized by a new, facile, ambient pressure triethylene glycol based solution chemical route using indium(III) chloride and selenium powder as precursors. The growing morphology, crystallization, chemical stoichiometry and light absorption property of the In2Se3 products synthesized were characterized by TEM, HRTEM, FESEM, XRD, EDX and UV–vis–NIR measurements. Multi-morphological growth of the nano-structured In2Se3 in triethylene glycol based solution syntheses with changed assisting agents and reaction styles was demonstrated. [Display omitted] •Multimorphological growth of In2Se3 was demonstrated based on solution chemistry.•A new, facile, low cost and fast air pressure TEG based solution process was used.•Nanoparticles, flower-like shaped and sheet-shaped nanocrystals were synthesized.•Morphology, crystallization, stoichiometry and light absorption was characterized.•Solution growth of β-In2Se3 nanosheets was firstly reported by this submission.
