AB  - Nowadays a large variety of applications are based on solid nanoparticles dispersed in liquids-so called nanofluids. The interaction between the fluid and the nanoparticles plays a decisive role in the physical properties of the nanofluid. A novel approach based on the nonradiative energy transfer between two small luminescent nanocrystals (GdVO4:Nd3+ and GdVO4:Yb3+) dispersed in water is used in this work to investigate how temperature affects both the processes of interaction between nanoparticles and the effect of the fluid on the nanoparticles. From a systematic analysis of the effect of temperature on the GdVO4:Nd3+. GdVO4:Yb3+ interparticle energy transfer, it can be concluded that a dramatic increase in the energy transfer efficiency occurs for temperatures above 45 degrees C. This change is properly explained by taking into account a crossover existing in diverse water properties that occurs at about this temperature. The obtained results allow elucidation on the molecular arrangement of water molecules below and above this crossover temperature. In addition, it is observed that an energy transfer process is produced as a result of interparticle collisions that induce irreversible ion exchange between the interacting nanoparticles.

AB  - Nanoparticle-mediated photothermal therapy (NP-PTT) constitutes a flexible, highly selective, cost effective, and accurate tool for cancer treatment alone or in combination with other therapies such as radiotherapy or chemotherapy. The future application of NP-PTT in real life mainly depends on the design and synthesis of novel multifunctional nanoparticles that could overcome the current limitations of NP-PTT such as limited penetration depth and absence of therapy control. In this work, ultrasmall (approximate to 2.4 nm) NdVO4 stoichiometric (100% constituent Nd3+ ions) nanoparticles are reported, which are capable of in vivo sub-tissue localized heating under 808 nm optical excitation while providing, simultaneously, the possibility of high penetration near-infrared fluorescence imaging. Ultrasmall stoichiometric NdVO4 nanoparticles have evidenced a superior light-to-heat conversion efficiency. This is explained in terms of their large absorption cross-section at 808 nm (consequence of the particular spectroscopic properties of neodymium ions in NdVO4 and of the high neodymium content) as well as to their ultrasmall size that leads to large nonradiative decay rates. Results included in this work introduce ultrasmall, NdVO4 stoichiometric nanoparticles to the scientific community as multifunctional photothermal agents that could be considered as an alternative to traditional systems such as metallic, organic, or carbon-based nanoparticles.
