在这项研究中，使用天然钠长石为底物的高温固态方法成功地制备了掺Tb3 +的天然钠长石（NaAlSi3O8）荧光粉。NaAlSi3O8的能量色散X射线光谱分析（EDX）表明存在0.03 wt％的Eu元素，元素分布图分析表明痕量Eu在矿物中的分布是聚集的。详细讨论了天然含钠Eu长石和合成钠长石NaAlSi3O8：Eu3 +，Tb3 +荧光粉的晶体结构和发光性能。样品的晶体结构分析表明，天然基质中的Na +被掺杂的Tb3 +部分取代。对样品的光致发光特性的研究表明，Eu在天然矿物中不会形成发光中心，然而，掺杂Tb3 +后，Eu3 +在615nm处出现了很强的特征峰，随着Tb3 +浓度的增加，Eu3 +在615nm处出现了特征峰。根据以上光谱结果，获得了从Tb3 +到Eu3 +的能量转移。通过颜色坐标的测量和分析，发现随着Tb3 +浓度的增加，样品的发光颜色可以在绿色到红色区域进行调节。NaAlSi3O8：Eu3 + Tb3 +荧光粉具有潜在的应用价值。发现随着Tb3 +浓度的增加，样品的发光颜色可以在绿色到红色区域进行调节。NaAlSi3O8：Eu3 + Tb3 +荧光粉具有潜在的应用价值。发现随着Tb3 +浓度的增加，样品的发光颜色可以在绿色到红色区域进行调节。NaAlSi3O8：Eu3 + Tb3 +荧光粉具有潜在的应用价值。

Rare earth ion Tb3+ doped natural sodium feldspar (NaAlSi3O8) Luminescent properties and energy transfer.

In this study, Tb3+-doped natural sodium feldspar (NaAlSi3O8) phosphors have been successfully prepared using high-temperature solid-state method with natural sodium feldspar as a substrate. Energy-dispersive X-ray spectrometry analysis (EDX) of NaAlSi3O8 showed that 0.03 wt% of Eu element was present, and elemental distribution mapping analysis showed that the distribution of trace Eu in minerals was aggregated. The crystal structure and luminescence properties of the natural sodium Eu-containing feldspar and synthetic sodium feldspar NaAlSi3O8:Eu3+, Tb3+ phosphors are discussed in detail. The crystal structure analysis of the samples showed that the Na+ in the natural matrix was partly replaced by the doped Tb3+. Studies on the photoluminescence properties of the samples indicate that Eu does not form a luminescent center in the natural mineral, however, the strong characteristic peak of Eu3+ at 615 nm appears after doping with Tb3+ and the peak at 615 nm increases with the increase of Tb3+ concentration. According to the above spectral results, the energy transfer from Tb3+ to Eu3+ is obtained. Through the measurement and analysis of color coordinates, it is found that with the increase of Tb3+ concentration, the luminescence color of the samples can be regulated in the green to red region. NaAlSi3O8:Eu3+ Tb3+ phosphors has potential application value.
