Langbeinite-type K2Bi1-xZr(PO4)3:xSm3+ phosphors were synthesized by a conventional solid-state reaction. The samples were characterized by X-ray diffraction, ultraviolet visible diffuse reflectance spectroscopy, calculation based on the density functional theory (DFT), and photoluminescence spectroscopy. The DFT analysis reveals that K2BiZr(PO4)3 is an insulator with an indirect band gap of 4.26 eV, which can be used as a fluorescent host. The prepared phosphors can be efficiently excited by near-ultraviolet light in the region from 340 to 425 nm and show three dominant emission bands peaking at 562, 600 and 647 nm due to the 4G5/2→6HJ (J = 5/2, 7/2, and 9/2) transition of the Sm3+ activator, respectively. The optimum doping concentration of Sm3+ is 10% (in mole). It is expected that Sm3+-doped K2BiZr(PO4)3 can be used as an orange-reddish phosphor for illumination or displays.

采用常规固相反应合成了无水钾镁矾基荧光粉材料钐(+3)激活磷酸锆铋钾,并用X射线衍射、紫外-可见漫反射光谱、密度泛函理论计算(DFT)和光致发光谱等方法进行了研究。DFT计算表明,磷酸锆铋钾是一种具有间接带隙的绝缘体,带宽为4.26 eV,适合作为荧光主体材料。该荧光粉可被340~425 nm范围内近紫外光有效地激发,发射出一系列钐(+3)的特征发射峰。主要包括562、600、647 nm附近3个发射带,分别对应于钐(+3)离子4G5/2→6HJ(J = 5/2,7/2,9/2)的能级跃迁。通过改变x值制备了不同钐(+3)浓度的样品,并比较了其发射强度,得出钐(+3)的最佳掺杂浓度为10%(摩尔分数)。因此,钐(+3)激活磷酸锆铋钾材料可作为橙红色荧光粉在照明和显示领域具有一定的应用价值。

采用常规固相反应合成了无水钾镁矾基荧光粉材料钐(+3)激活磷酸锆铋钾,并用X射线衍射、紫外-可见漫反射光谱、密度泛函理论计算(DFT)和光致发光谱等方法进行了研究。DFT计算表明,磷酸锆铋钾是一种具有间接带隙的绝缘体,带宽为4.26 eV,适合作为荧光主体材料。该荧光粉可被340~425 nm范围内近紫外光有效地激发,发射出一系列钐(+3)的特征发射峰。主要包括562、600、647 nm附近3个发射带,分别对应于钐(+3)离子4G5/2→6HJ(J = 5/2,7/2,9/2)的能级跃迁。通过改变x值制备了不同钐(+3)浓度的样品,并比较了其发射强度,得出钐(+3)的最佳掺杂浓度为10%(摩尔分数)。因此,钐(+3)激活磷酸锆铋钾材料可作为橙红色荧光粉在照明和显示领域具有一定的应用价值。

Langbeinite-type K2Bi1-xZr(PO4)3:xSm3+ phosphors were synthesized by a conventional solid-state reaction. The samples were characterized by X-ray diffraction, ultraviolet visible diffuse reflectance spectroscopy, calculation based on the density functional theory (DFT), and photoluminescence spectroscopy. The DFT analysis reveals that K2BiZr(PO4)3 is an insulator with an indirect band gap of 4.26 eV, which can be used as a fluorescent host. The prepared phosphors can be efficiently excited by near-ultraviolet light in the region from 340 to 425 nm and show three dominant emission bands peaking at 562, 600 and 647 nm due to the 4G5/2→6HJ (J = 5/2, 7/2, and 9/2) transition of the Sm3+ activator, respectively. The optimum doping concentration of Sm3+ is 10% (in mole). It is expected that Sm3+-doped K2BiZr(PO4)3 can be used as an orange-reddish phosphor for illumination or displays.
