The equilibrium solubility of CsCl‐CeCl 3 ‐HCl (11%)‐H 2 O quaternary system at 25 °C has been determined by the physic‐chemical analysis method, and the phase diagram was plotted. Two new double salts 3CsCl · CeCl 3 · 3H 2 O and CsCl · CeCl 3 · 4H 2 O obtained from the complicated system were identified and characterized by XRD, TG‐DTA, DSC, UV and fluorescence spectroscopy. Studies on the fluorescence excitation and emission show that 3CsCl · CeCl 3 · 3H 2 O and CsCl · CeCl 3 · 4H 2 O have upconversion luminescence of infrared‐visible range, and the upconversion emission intensity increases with the increase of ratio of CeCl 3 in CsCl.
