- Abstract
Here, we report synthesis of pure crystalline nanopowders of yttrium orthophosphate YErPO with xenotime-type structure and hydrate of yttrium orthophosphate YErPO⋅0.8HO with rhabdophane-type structure using microwave-hydrothermal treatment of freshly precipitated gels. To establish phase composition of the synthesized nanopowders, we have carried out XRD analysis. Also, we have investigated their morphology by means of TEM and SAXS. We have registered scattered reflection spectra for synthesized YErPO and YErPO⋅0.8HO powders. Also, we have obtained luminescent spectra of these nanocrystalline samples for I → I transition of Er ion with excitation of I level. We have proposed the mode of application of nanocrystalline powders YErPO and YErPO⋅0.8HO for the development of composite materials based on polymer capsules that are being used in targeted drug delivery.
