Abstract:The final objective of this work is to measure the internal temperature of a plant by using the thermometric photoluminescence properties of the Erbium doped KYb(WO4)2 nanocrystals. The synthesis of the nanocrystals is performed by the modified Pechini method. An X-ray powder analysis and a Le Bail refinement have been realized to obtain structural information of the prepared nanocrystals. Also, transmission electron microscopy has been performed to obtain the particle size and size distribution of the obtained samples. Furthermore, a spectroscopic characterization of different quantities of Er3+ doping has been performed in order to study the sample with major visible intensity in order to be used as a temperature photoluminescence sensor. To end, also an optical spectroscopic study was realized of the roots from the plants that were previously watered with a nanocrystal water dispersion.
