A group of upconverting Ba2V2O7 barium pyrovanadate materials doped with Yb³⁺, Ho³⁺ was synthesized by hydrothermal method in a basic environment in order to promote the formation of [V2O7]⁴⁻ groups. The structural studies accompanied with the Rietveld analysis confirmed the excellent purity of the undoped matrix, while the increase in the phase co...

Due to the ongoing need to create phosphors with the appropriate emission color for the production of light emitting diodes, we decided to synthesize a series of multicolour microphosphors with tunable visible emissions, depending on the composition of dopant ions. In this work, we investigated the structure, morphology, and luminescent properties...

A series of dual-mode nanomaterials based on Ba2LaV3O11:Yb³⁺, Er³⁺, Bi³⁺, with different bismuth content were synthesized using the hydrothermal method. Various analytical methods, such as x-ray diffraction (XRD) with additional detailed Rietveld analysis, transmission electron microscopy (TEM), inductively coupled plasma mass spectroscopy (ICP-MS)...

According to our knowledge, rare earth based upconverting ternary vanadates are synthesized by the hydrothermal method for the first time. This facile procedure offers an alternative approach to obtaining nanomaterials with the desired crystal structure, while omitting calcination step as to prevent from particle size growth and their agglomeration...
