Popis:	This study reports on the synthesis of Eu and Li-codoped zirconia ZrO2 nanoparticles (NPs) using a facile urea precipitation method. The morphology, structural and optical properties of prepared Eu, Li-codoped ZrO2 NPs were analyzed by transmission electron microscope (TEM), X-ray diffraction (XRD), and photoluminescence (PL), respectively. As the main goal of this study, we investigated the effects of Li-codoping on the optical properties of Eu-doped ZrO2 NPs. Strong eye-visible red emission due to 5D0→7F1 and 5D0→7F2 transitions was detected under continuous 250 nm excitation. Thanks to excellent optical properties, prepared Eu, Li-codoped ZrO2 NPs can be used for solid-state lighting, security printing, etc
