Hydrothermal Synthesis, Photoluminescence Property and Superhydrophobicity of In(OH)3

In this work, we fabricated indium hydroxide (In (OH)3) nanocubes from In (NO3)3 and urea through hydrothermal method. NH4OH form the hydrolysis of urea acts as the OH¯ provider. The resultant products were characterized by X-ray diffraction (XRD), scanning electronic microscope (SEM), photoluminescence (PL) spectra and contact angle meter. It was observed that the In (OH)3 nanocubes showed superhydrophobicity with water contact angle 161.9° after modified with fluoroalkylsilane (FAS, CF3(CF2)7CH2CH2Si (OCH3)3), and exhibited PL peak at about 529 nm, corresponding to the deep level emission.
