摘要

用共沉淀法制备了Sr3La(PO4)3:Eu3+ (SLP:Eu3+)荧光粉，该荧光粉在生物窗口区发出红色可见光并伴有近红外(NIR)发光。讨论了合成温度和Eu3+掺杂浓度对荧光粉性能的影响。当Eu3+掺杂量为0.7 mol%时，在1200℃下退火2 h，结晶度最佳，晶粒尺寸约为1 μm。与SLP:0.01 Eu3+相比，SLP:0.07 Eu3+在615 nm和705 nm的光致发光强度分别提高了4.95倍和3.97倍。具有高近红外发射的红色SLP:Eu3+荧光粉是生物图像和生物传感器应用的潜在候选材料。

Synthesis and Characteristics of Sr3La(PO4)3:Eu3+ Phosphor with Luminescence in NIR Biological Window

The Sr3La(PO4)3:Eu3+ (SLP:Eu3+) phosphor was prepared with the coprecipitation method, which emited red visible-light along with a near-infrared (NIR) luminescence in the biological window region. The influence of synthesis temperature and Eu3+ doping concentration on the characteristics of the phosphor was discussed. The optimal crystallinity was obtained when the phosphor was doped with 0.7 mol% of Eu3+ and annealed at 1200 °C for 2 h. The particle size was approximately 1 μm. As compared with the SLP:0.01 Eu3+, the photoluminescence intensity of the SLP:0.07 Eu3+ increased by 4.95-fold at wavelength of 615 nm and 3.97- fold at 705 nm. The red SLP:Eu3+ phosphor with a high NIR emission is a potential candidate material for bio-image and bio-sensor applications.
