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.
