Ba₂La₂ZnW₂O₁₂:xMn⁴⁺ (BLZWO:xMn⁴⁺) (0 ≤ x ≤ 1.2 mol%) are prepared via the solid state reaction method under air conditions. The crystal phases and optical properties of all samples are investigated. The yellow emission of BLZWO is observed with the chromaticity coordinates (0.3940, 0.4389), and its emission spectrum covers the region from 380 to 810 nm owing to the W⁶⁺ - O^2- transition. When the excitation wavelength is 344 nm, BLZWO:xMn⁴⁺ show an adjustable photo-luminescence characteristic by altering the Mn⁴⁺ concentration owing to the energy transfer from [WO₆] group to Mn⁴⁺ ions. With excitation at 514 nm, BLZWO:xMn⁴⁺ only show red emission. The excitation spectrum of BLZWO:Mn⁴⁺ with peaks at 344 and 514 nm is in the region from 210 to 600 nm and its emission spectrum with peak at 704 nm are observed in the range of 625 - 800 nm. The lifetimes of BLZWO:xMn⁴⁺ reduce successively with adding Mn⁴⁺ concentration. The results are good for the basic research on luminescence characteristics of Mn⁴⁺ ion.

的Ba ₂的La ₂ ZnW ₂ ö ₁₂：XMN ⁴⁺（BLZWO：XMN ⁴⁺）（0≤ X ≤1.2摩尔％），通过空气条件下的固相反应法来制备。研究了所有样品的晶相和光学性质。观察到BLZWO的黄色发射，其色度坐标为（0.3940，0.4389），由于W ⁶⁺ -O ^2-跃迁，其发射光谱覆盖了380至810 nm的区域。当激发波长为344 nm时，BLZWO：xMn ⁴⁺通过改变Mn ⁴⁺表现出可调节的光致发光特性由于从[WO ₆ ]基团到Mn ⁴⁺离子的能量转移而导致浓度升高。在514 nm处激发时，BLZWO：xMn ⁴⁺仅显示红色发射。在344和514nm处具有峰的BLZWO：Mn ⁴⁺的激发光谱在210至600nm范围内，并且在625-800nm的范围内观察到其在704nm处具有峰的发射光谱。BLZWO：xMn ⁴⁺的寿命随着Mn ⁴⁺浓度的增加而连续降低。该结果为Mn ⁴⁺离子发光特性的基础研究奠定了基础。
