The research of high-efficiency trichromatic phosphors based on vltraviolet/near-ultraviolet (UV/n-UV) excitation is of great significance for the development of white light-emitting diode (LED) applications. A series of Ce3+, Tb3+ or Eu3+ single-doped CaxMgyAlmSinOz (i.e., Ca2Mg0.25Al1.5Si1.25O7, Ca2Mg0.5AlSi1.5O7, Ca2Mg0.75Al0.5Si1.75O7, and Ca20Al26Mg3Si3O68) trichromatic phosphors were synthesized by a high-temperature solid-phase method. The crystal structure and band gap of samples were investigated by Rietveld refinement, crystal structure simulation and density functional theory calculation, and the effect of stoichiometry-regulating crystal field on the luminescent performance was analyzed. High-quality blue, green and red trichromatic phosphors with quantum efficiencies of 28.13, 26.42 and 26.75, fluorescence lifetime of 42.23 ns, 2.88 ms and 2.21 ms, as well as a good thermal stability were selected to compare their luminescent performance. Finally, the prototypes of white LED were fabricated with the trichromatic phosphors for UV chip, and their performance parameters (i.e., luminous efficiency, correlated color temperature and color rendering index) were tested. The results show that these phosphors have a promising potential in the application of UV-excited white LEDs.

基于紫外/近紫外光激发的高效三基色荧光粉的研发对于白光LED的应用发展具有重要意义。通过高温固相法合成一系列Ce3+、Tb3+和Eu3+单掺杂CaxMgyAlmSinOz(Ca2Mg0.25Al1.5Si1.25O7, Ca2Mg0.5AlSi1.5O7, Ca2Mg0.75Al0.5Si1.75O7, Ca20Al26Mg3Si3O68)的三基色荧光粉。通过Rietveld精修、晶体结构模拟和密度泛函理论计算等对样品晶体结构和带隙结构进行研究,分析了化学计量数调控晶体结构及其对发光性的影响。结果表明:通过发光性能对比,挑选出优质蓝、绿、红三基色荧光粉Ca2Mg0.25Al1.5Si1.25O7:0.06Ce3+、Ca2Mg0.5AlSi1.5O7:0.06Tb3+和Ca2Mg0.25Al1.5Si1.25O7:0.07Eu3+,三者量子效率分别为28.13、26.42和26.75,荧光寿命分别为42.23 ns、2.88 ms和2.21 ms,发光热稳定性良好;最后,将三基色荧光粉与紫外芯片结合制作了白光发光二极管(LED),并测试其发光效率、相关色温和显色指数等性能参数,结果表明这些荧光粉在紫外激发白光LED中具有潜在的应用前景。

基于紫外/近紫外光激发的高效三基色荧光粉的研发对于白光LED的应用发展具有重要意义。通过高温固相法合成一系列Ce3+、Tb3+和Eu3+单掺杂CaxMgyAlmSinOz(Ca2Mg0.25Al1.5Si1.25O7, Ca2Mg0.5AlSi1.5O7, Ca2Mg0.75Al0.5Si1.75O7, Ca20Al26Mg3Si3O68)的三基色荧光粉。通过Rietveld精修、晶体结构模拟和密度泛函理论计算等对样品晶体结构和带隙结构进行研究,分析了化学计量数调控晶体结构及其对发光性的影响。结果表明:通过发光性能对比,挑选出优质蓝、绿、红三基色荧光粉Ca2Mg0.25Al1.5Si1.25O7:0.06Ce3+、Ca2Mg0.5AlSi1.5O7:0.06Tb3+和Ca2Mg0.25Al1.5Si1.25O7:0.07Eu3+,三者量子效率分别为28.13、26.42和26.75,荧光寿命分别为42.23 ns、2.88 ms和2.21 ms,发光热稳定性良好;最后,将三基色荧光粉与紫外芯片结合制作了白光发光二极管(LED),并测试其发光效率、相关色温和显色指数等性能参数,结果表明这些荧光粉在紫外激发白光LED中具有潜在的应用前景。

The research of high-efficiency trichromatic phosphors based on vltraviolet/near-ultraviolet (UV/n-UV) excitation is of great significance for the development of white light-emitting diode (LED) applications. A series of Ce3+, Tb3+ or Eu3+ single-doped CaxMgyAlmSinOz (i.e., Ca2Mg0.25Al1.5Si1.25O7, Ca2Mg0.5AlSi1.5O7, Ca2Mg0.75Al0.5Si1.75O7, and Ca20Al26Mg3Si3O68) trichromatic phosphors were synthesized by a high-temperature solid-phase method. The crystal structure and band gap of samples were investigated by Rietveld refinement, crystal structure simulation and density functional theory calculation, and the effect of stoichiometry-regulating crystal field on the luminescent performance was analyzed. High-quality blue, green and red trichromatic phosphors with quantum efficiencies of 28.13, 26.42 and 26.75, fluorescence lifetime of 42.23 ns, 2.88 ms and 2.21 ms, as well as a good thermal stability were selected to compare their luminescent performance. Finally, the prototypes of white LED were fabricated with the trichromatic phosphors for UV chip, and their performance parameters (i.e., luminous efficiency, correlated color temperature and color rendering index) were tested. The results show that these phosphors have a promising potential in the application of UV-excited white LEDs.
