Wet chemical method was employed for the synthesis of novel RE ³⁺ (RE = Ce, Dy, Eu)-doped Na₃Ca₂(SO₄)₃Cl phosphors. Structure and bonding between each element of the sample and morphology of the sample were analyzed using X-ray diffraction (XRD) and scanning electron microscopy (SEM), which showed that the samples were crystallized in a well-known structure. Photoluminescence study of Na₃Ca₂(SO₄)₃Cl:Dy³⁺ shows emission bands at 484 and 577 nm due to ⁴F_9/2→⁶H_15/2 and ⁴F_9/2→⁶H_13/2 transitions, respectively, keeping excitation constant at 351 nm because of ⁶H_15/2→⁶P_7/2 , whereas emission peak for Na₃Ca₂(SO₄)₃Cl:Ce³⁺ phosphors is observed at 349 nm, monitoring excitation under peak at 267 nm. The emission of Eu in Na₃Ca₂(SO₄)₃Cl phosphor is very characteristic and intense. Excitation of Eu is observed due to ⁷F₀→⁵L₆ and one more excitation which is very weak. Emission line at 594 and 617 nm corresponds to the forced electric dipole ⁵D₀ →⁷F₁ and ⁵D₀ →⁷F₂, respectively.

采用湿化学法合成了新型稀土^{3 +}（RE = Ce，Dy，Eu）掺杂的Na ₃ Ca ₂（SO ₄）₃ Cl荧光粉。使用X射线衍射（XRD）和扫描电子显微镜（SEM）分析样品的每个元素之间的结构和键合以及样品的形态，这表明样品以众所周知的结构结晶。Na ₃ Ca ₂（SO ₄）₃ Cl：Dy ^3+的光致发光研究表明，由于⁴ F ⁹ /2 → ⁶ H _15/2和⁴ F _9/2而在484和577 nm处具有发射带。⁴ ˚F _9/2 → ⁶ ħ _13/2跃迁分别保持激发在351nm处，由于恒定⁶ ħ _15/2 → ⁶ P _7/2，而其Na发射峰₃的Ca ₂（SO ₄）₃ CL：在349 nm处观察到Ce ³⁺荧光粉，监测267 nm峰值下的激发。Na ₃ Ca ₂（SO ₄）₃ Cl荧光粉中Eu的发射非常有特征且强烈。由于⁷ F ₀ → ⁵观察到Eu的激发L ₆和另一个很弱的激励。594和617 nm处的发射线分别对应于强制电偶极子⁵ D ₀ → ⁷ F ₁和⁵ D ₀ → ⁷ F ₂。
