The trivalent state of the Eu ion is of particular importance in developing optoelectronic devices due to its broad spectrum of visible emissions. Although the shielding effect of 4f electrons in the lanthanide series is well-known, changes in the symmetry of the chemical environment surrounding Eu³⁺ ions can significantly impact their luminescence. In this presentation, I will explore the synthesis of a europium-doped ZnO thin film using the Spray-Pyrolysis technique and investigate how the host ZnO crystallinity influences europium's optical emissions. This study employs simultaneous X-ray Diffraction and photoluminescence spectroscopy to examine the effects of varying hydrostatic pressures, with measurements conducted at the Sirius synchrotron facilities.
