Zirconia (ZrO2) has been intensively studied as an important ceramic material, and numerous technological applications have been found. The present work deals with synthesizing and characterizing the phase transition (cubic vs tetragonal) and photoluminescence emissions of ZrO2:xTb3+ (x = 1,2,4 and 8 mol%). The samples formed by the complex polymerization were thoroughly characterized for physicochemical properties such powder by X-ray diffraction (XRD), and Raman and diffuse reflectance spectroscopies. First-principle calculations at the density functional theory level were performed to complement and rationalize the experimental results. An energy transfer mechanism which promoted the f-f transitions and emitted strong characteristic emissions of Tb3+ is discussed in detail. A ZrO2 lattice acts as an effective sensitizer and the green light emission and the color purity were controlled by the concentration of the Tb3+ cations. Moreover, this study enables us to construct a more consistent picture of the doping process of Tb3+ in ZrO2 and provides a new approach for fabricating a multifunctional material and prospective application in lighting devices.
