Abstract : We present a new generation of nanotracers with persistent luminescence properties in the red-near IR range for small animal imaging. Silicates, oxysulfides and calcium phosphates nanoparticles doped with transition metal and lanthanide ions were developed in this aim. We have focused our attention in this paper on the biocompatible TCP/HAp phosphate compounds doped with Eu, Mn, Dy and on the Gd2O2S:Eu, Mg, Ti materials in the form of nanoparticles. All the nanosensors were hydrothermally synthesized and if the phosphate has a very high interest due to its biocompatibility Gd2O2S:Eu, Mg, Ti was investigated as a multimodal agent for possible in vivo optical imaging and MRI imaging. © (2015) COPYRIGHT Society of Photo-Optical Instrumentation Engineers (SPIE).
