| 摘 要： | The equilibrium solubility of CsCl-CeCl3-HCl(11%)-H2O qua-ternary system at 25℃ has been determined by the physicchemical analysis method ,and the phase diagram was plotted, Two new double salts 3CsCl.CeCl3.3H2O and CsCl.CeCl3.4H2O 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.CeCl3.3H2O and CsCl.CeCl3.4H2O have upconversion luminescence of infrared-visible range,and the upconversion emission intensity increases with the increase of ratio of CeCl3 in CsCl.

| Abstract: | The equilibrium solubility of CsCl‐CeCl3‐HCl (11%)‐H2O 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 · CeCl3 · 3H2O and CsCl · CeCl3 · 4H2O 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 · CeCl3 · 3H2O and CsCl · CeCl3 · 4H2O have upconversion luminescence of infrared‐visible range, and the upconversion emission intensity increases with the increase of ratio of CeCl3 in CsCl. |
