Phosphor-converted white light emitting diodes (w-LEDs), with high luminous efficiency, low energy consumption, extended lifetime, and eco-friendly nature, have revolutionized various industries. Among them, an alkaline earth silicate-based phosphor host, Na₄CaSi₃O₉, shows good crystal structure stability and flexible properties for diverse application. Here, Ce³⁺/Li⁺ singly doped and Ce³⁺/Li⁺/Tb³⁺ co-doped Na₄CaSi₃O₉ phosphors are fabricated by the standard solid-state reaction approach. The Ce³⁺/Li⁺-activated phosphors show strong absorption within 200–400 nm and exhibit a blue emission centered at 423 nm. The quenching concentration of Ce³⁺ appears at x = 0.05 and can be attributed to the dipole–quadrupole interaction. When Tb³⁺ ions are co-doped, the Na₄CaSi₃O₉:Ce³⁺,Li⁺,Tb³⁺ phosphor emission can be adjusted from blue to green under the irradiation of 365 nm through the dipole–dipole interaction induced energy transfer from Ce³⁺ to Tb³⁺ ions with a maximum value of 28.32%. This study highlights the Na₄CaSi₃O₉:Ce³⁺,Li⁺,Tb³⁺ phosphors as a new and efficient material for w-LED applications.

磷光转换白光发光二极管（w -LEDs）具有高发光效率，低能耗，延长使用寿命和生态友好的特性，已经彻底改变了各个行业。其中，碱土硅酸盐基磷光体基质Na ₄ CaSi ₃ O ₉具有良好的晶体结构稳定性和灵活的性能，可用于各种应用。在此，通过标准的固态反应方法制备了Ce ³⁺ / Li ⁺单掺杂和Ce ³⁺ / Li ⁺ / Tb ³⁺共掺杂的Na ₄ CaSi ₃ O ₉荧光粉。铈³⁺ /锂⁺活化的磷光体在200–400 nm范围内显示强吸收，并显示以423 nm为中心的蓝色发射。Ce ³⁺的猝灭浓度出现在x  = 0.05，并且可以归因于偶极-四极相互作用。当共掺杂Tb ³⁺离子时，通过诱导的偶极-偶极相互作用，可以在365 nm的辐射下将Na ₄ CaSi ₃ O ₉：Ce ³⁺，Li ⁺，Tb ³⁺磷光体的发射从蓝色调整为绿色。从Ce ³⁺到Tb ³⁺离子的能量转移，最大值为28.32％。这项研究突出了Na ₄ CaSi₃ O ₉：Ce ³⁺，Li ⁺，Tb ³⁺磷光体是w- LED应用的新型高效材料。
