采用高温固相反应法合成了Mn 4+，Cr 3+单掺杂和Mn 4+，Cr 3+共掺杂的BaMgAl 10 O 17荧光粉。Mn 4+和Cr 3+离子在紫外-可见光范围内都有较宽的激发带，Mn 4+和Cr 3+离子的发射峰分别位于660 nm和694 nm。通过改变Mn 4+，Cr 3+共掺杂BaMgAl 10 O 17荧光粉中Cr 3+或Mn 4+的掺杂浓度，可以调节Mn 4+和Cr 3+的相对发光强度，以更好地匹配不同植物光合作用所需的光。此外，共掺杂荧光粉中Mn 4+和Cr 3+的发光强度比与激发波长在320 ~ 530 nm范围内的特定关系表明，可以通过测量Mn 4+和Cr 3+之间的发光积分强度比来获知激发波长。结果表明，Mn 4+，Cr 3+共掺杂BaMgAl 10 O 17荧光粉不仅可以用作植物生长光谱转换器，还可以用作波长探测器。
Mn 4+, Cr 3+ single-doped and Mn 4+, Cr 3+ co-doped BaMgAl 10 O 17 phosphors were synthesized via a conventional high-temperature solid-state reaction method. Both Mn 4+ and Cr 3+ ions show broad excitation band extending from ultraviolet to visible light range, and the emission band peaks at 660 nm for Mn 4+ ion and at 694 nm for Cr 3+ ion. The relative intensity of the luminescence of Mn 4+ and Cr 3+ can be adjusted by changing the co-doped Cr 3+ or Mn 4+ concentration in the Mn 4+, Cr 3+ co-doped BaMgAl 10 O 17 phosphor to better match the required light for photosynthesis of different plants. Moreover, the specific relationship between the luminous intensity ratio of Mn 4+ and Cr 3+ and the excitation wavelength in the region of 320 to 530 nm in the co-doped phosphor suggests that the excitation wavelength can be known by measuring the emission integral intensity ratio between Mn 4+ and Cr 3+. The results show that the Mn 4+, Cr 3+ co-doped BaMgAl 10 O 17 phosphors can not only be used as plant growth spectral converter, but also wavelength detector.
