چکیده انگلیسی
We have developed a novel biomolecule-assisted hydrothermal method to prepare Sb2S3 and Bi2S3 nanocrystals with various sizes and shapes, in which cysteine combined with other sulfur source can exert the synergistic effect on products. The samples were characterized XRPD, TEM, HRTEM, FESEM, and PL techniques. First, we prepared a series of Sb2S3 and Bi2S3 nanocrystals by simply adjusting the composition of sulfur sources under hydrothermal conditions. Then, we studied the elevated-temperature oxidation behavior of these sulfides in air, which can lead to the formation of α-Sb2O4 and Bi2O3 samples at 600 °C for 3 h. The optical properties of the α-Sb2O4 and Bi2O3 samples were also discussed.
