In this paper, the carbon dioxide carbonization method was applied to the separation of rare earths and calcium in the solution, as well as the preparation of rare earth oxides with a large specific surface. It is shown that the process of CO₂ carbonization of solution includes reactions such as the dissolution, diffusion and ionization of CO₂, the carbonate precipitation of rare earth ions, and the neutralization of hydrogen ions. At a pH of 4.5, the carbonization precipitation rate is effectively controlled, enabling homogeneous precipitation and ensuring both high precipitation yield and rare earth oxides purity. In this way, the crystallization of carbonization products is a process dominated by the oriented attachment theory and coexisting with the Ostwald ripening theory, resulting in abundant pores formed by multiple layers of stacking in the products. With the optimal carbonization conditions, the rare earth precipitation yield solution reaches 99.32%. The obtained carbonization products are crystalline (LaCe)(CO₃)₃·8H₂O, and the purity of the rare earth oxides is as high as 99.22 wt%. The specific surface area of the rare earth oxides reaches 94.7 m²/g, and its adsorption efficiency for tetracycline hydrochloride in solution can reach 92.6% in a short time.

Therefore, investigating the removal of SMZ is of critical importance. In order to investigate the effect of rare earth metal doping on the performance of activated persulfate oxidative degradation of SMZ, BiFeO₃ with different Ce doping amounts was successfully prepared by a hydrothermal method. Then, it was characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), scanning transmission electron microscopy (STEM) and Brunauer–Emmett–Teller (BET) method. The performance of porous Ce/BiFeO₃ in the catalytic activation of persulfate (PMS) for the degradation of SMZ in water was investigated using SMZ solution as a simulated wastewater. The impact of Ce doping rate, catalyst dosage, temperature variations, common anions, natural organic matter, and PMS concentration on SMZ removal was systematically evaluated. The characterization results show that the octahedral rhombic structure of Ce can be observed on the surface of this doped catalyst, and Ce doping does not change the crystalline shape of Ce/BiFeO₃. The specific surface area of the doped catalyst increases, accompanied by an enlargement of pore size, thereby enhancing the catalyst's adsorption capacity and resistance to contamination by SMZ. Under the optimal conditions of 25 °C, SMZ concentration of 20 mg/L, 0.8 g/L PMS and 0.3 g/L 0.05Ce/BiFeO₃ catalyst, the removal rate of SMZ reaches approximately 95% within 35 min of reaction time.

However, the poor modulation of emission restricts their applications, and it is highly desirable to explore stable and efficient double perovskites with multimode luminescence and adjustable spectra for multifunctional photoelectric applications. Herein, the rare earth ions Ln³⁺ (Er³⁺ and Ho³⁺)-doped Cs₂NaYCl₆:Sb³⁺ crystals were synthesized by a simple solvothermal route. The X-ray diffraction pattern (XRD), energy-dispersive spectroscopy (EDS), X-ray photoelectron spectroscopy (XPS), and elemental mapping images demonstrate that the Sb³⁺, Er³⁺, and Ho³⁺ ions have been homogeneously incorporated into the Cs₂NaYCl₆ crystals. As anticipated, the emission spectra of Cs₂NaYCl₆:Sb³⁺/Ln³⁺ are composed of two bands. One broad blue band derives from self-trapped exciton (STE) in [SbCl₆]³⁻ octahedra while another group of emission peaks stems from the f–f transitions of Ln³⁺ ions. The emission colors of Cs₂NaYCl₆:Sb³⁺/Ln³⁺ phosphors can be tuned in a wide range by modulating the doping concentrations of Ln³⁺ ions. The efficient energy transfer from STE to Ln³⁺ is the key point to achieving the efficient and tunable emissions Cs₂NaYCl₆:Sb³⁺/Ln³⁺ samples.
