Luminescent nanocrystals in the rare-earth niobate-zirconia system formed via hydrothermal method

This graphical abstract shows the excitation and emission spectra and a transmission electron microscopy image of nanocrystals (with composition based on the rare-earth niobates (Ln3NbO7, Ln=Y, Eu) and zirconia (ZrO2) that were composed of 50 mol% Ln3NbO7 and 50 mol% ZrO2) formed via hydrothermal route.
