CaNb₂O₆:Tb³⁺ green phosphors have been successfully fabricated via the traditional solid-state synthesis, where the nanocrystalline TbB₆ is used as efficient activator. The doping effects of nanocrystalline TbB₆ on the phase composition, the microstructure and photoluminescence of as-prepared phosphors were characterized by means of Rietveld refinement XRD, FESEM and photoluminescence measurements. As a result, all the synthesized CaNb₂O₆:Tb³⁺ phosphors are composed by the single phase of CaNb₂O₆. The photoluminescence (PL) spectroscopy shows that the maximum emission intensity occurred when the nanocrystalline TbB₆ doping concentration is x = 0.06. Moreover, this phosphor keep the emission intensity remains about 43.3% of 300 K when its emission temperature increase to 423 K. Additionally, the white LED is fabricated by mixing present green phosphor with commercial blue and yellow phosphors, showing a white LED with the color temperature of 5152 K. On the basis of above mentioned, Ca_0·94Nb₂O₆:0.06TbB₆ phosphor can be applied as a potential green phosphor for high-performance white LED.

CaNb ₂ O ₆ :Tb ³⁺绿色荧光粉已通过传统的固态合成成功制造，其中纳米晶 TbB ₆用作有效的活化剂。通过Rietveld精修XRD、FESEM和光致发光测量表征了纳米晶TbB ₆掺杂对制备的荧光粉的相组成、微观结构和光致发光的影响。结果，所有合成的CaNb ₂ O ₆ :Tb ³⁺荧光粉均由单相CaNb ₂ O _{6 组成。}. 光致发光 (PL) 光谱表明，当纳米晶 TbB ₆掺杂浓度为 x = 0.06时，出现最大发射强度。此外，当其发射温度增加到 423 K 时，该荧光粉保持 300 K 的约 43.3% 的发射强度。 此外，白色 LED 是通过将现有绿色荧光粉与商业蓝色和黄色荧光粉混合制成的，显示出具有颜色的白色 LED温度为5152 K。在上述基础上，Ca _0·94 Nb ₂ O ₆ :0.06TbB ₆荧光粉可用作高性能白光LED的潜在绿色荧光粉。
