Physico-chemical characterizations of Cr doped persistent luminescence nanoparticles
Abstract
Persistent luminescence nanoparticles have recently been proposed as innovative optical probes for small animal in vivo imaging. The main advantage of such probes is their ability to emit light for a long time after the end of their excitation, allowing in vivo imaging with low background. This work reports new information on the physico-chemical characterizations of Cr doped ZnGa2O4 nanoprobes in terms of synthetic procedure, luminescence properties as well as colloidal stabilities in different aqueous media and over the time.
