Three‐dimensional Bi 2 S 3 with different morphology of flower‐like, waxberry like and hydrangea like on the tin‐doped indium oxide substrate has been produced from one‐step aqueous solution at low temperature (40–70°C) and fixed pH of 0.81 for 24 h. The UV–vis measurement showed that the absorption spectrums of obtained Bi 2 S 3 crystals were occurred blue shift compared to the bulk orthorhombic Bi 2 S 3 (1.3 eV). With the increase in temperature, the crystallinity of Bi 2 S 3 films was gradually improved. When the temperature went to 55°C, the best conductivity was obtained.
