Porous Nd(2)(SiO(4))(3) nanoparticles were successfully synthesized by a controlled route. This kind of silicate nanoparticle could be excited by near-infrared (NIR) radiation (808 nm) and triggered a NIR emission (1066 nm) at room temperature. By monitoring the 1066 nm emission, the long-lived luminescent lifetime was determined to be 19.5 mu s. These NIR nanoparticles with appropriate diameters (< 100 nm) were suitable for cell assays. MTT assays showed that the cytotoxicity of the porous Nd(2)(SiO(4)) (3) nanoparticles was very low. Therefore, these porous silicate nanoparticles are potential biosafe high-performance NIR biolabeling materials.
