The synthesis and luminescent properties of water colloidal solution of LiNdP4O12 nanocrystals were presented together with demonstrations of their suitability for bio-imaging, remote nano-thermometry and hyperthermal therapy bio-applications. Due to efficient and photostable luminescence at 860 nm under similar to 808 nm excitation, NPs luminescence was measured in chicken breast at down to 30 mm depths. Moreover temperature dependent spectroscopic features were used in order to remotely measure the temperature of the local environment. Simultaneously, the most heavily Nd3+ doped NCs demonstrated intentional heating - under 1.5 W of excitation power at 800 nm, local 60 K photo-induced temperature rise was observed. The experimental confirmation of bioimaging of LiNdP4O12 nanoparticles in HEK was presented. (C) 2016 Elsevier B.V. All rights reserved.
