Title: The pressure-induced phase transition studies of In{sub 2}S{sub 3} and In{sub 2}S{sub 3}:Ce nanoparticles

A novel method, gas–liquid phase chemical deposition is developed to prepare In{sub 2}S{sub 3} and In{sub 2}S{sub 3}:Ce nanoparticles. The structural, morphology and composition feature of these two nanoparticles is studied by XRD, HRTEM, and XPS. In situ high-pressure synchrotron X-ray diffraction studies were carried out by using a diamond-anvil cell. The doping does not influence the tetragonal-to-cubic phase transition path while results in a lower phase transition pressure of In{sub 2}S{sub 3}:Ce nanoparticles (4.3 GPa) than that of In{sub 2}S{sub 3} nanoparticles (7.1 GPa). The bulk moduli of tetragonal phases are B{sub 0}=87.1±4.3 GPa and B{sub 0}=55.6±4.1 GPa, respectively. The distinct high-pressure behaviors can be explained in term of the doped ions, causing lattice distortion and reducing structural stability of the In{sub 2}S{sub 3} nanoparticles and further accelerating the phase transition. - Graphical abstract: The phase transition of the In{sub 2}S{sub 3} and In{sub 2}S{sub 3}:Ce nanoparticles have been investigated for the first time by in situ high pressure synchrotron X-ray in a diamond anvil cell. Display Omitted - Highlights: • The high-pressure behaviors of In{sub 2}S{sub 3} and In{sub 2}S{sub 3}:Ce have been investigated. • The pressure-induced tetragonal-to-cubic phase transitions have been observed. • The phase transition pressuremore » of In{sub 2}S{sub 3}:Ce is lower than that of In{sub 2}S{sub 3} nanoparticles. • The distinct high-pressure behaviors are ascribed to the dopants. • The doping causes lattice distortion reducing the structural stability.« less
