N2 - This work reports the effect of Eu doping on the structural, morphological, linear, and nonlinear optical properties of Sn1−xEu xO2 (x = 0 to 0.10) thin films prepared using spray pyrolysis. The films crystallized in tetragonal structure and the crystallite size reduced due to Eu incorporation. The film morphology consisted of evenly distributed dense grains with trapezohedron or bipyramidal shape. The Eu doping reduced the transmittance and energy band gap of the deposited films. The photoluminescence (PL) emission spectra comprised the contributions from both the transitions related to the Eu3+ ions and the defects, such as oxygen vacancies and tin interstitials in the host lattice. The films also showed a near white light emission due to the different defect-related PL emissions. The Z-scan technique revealed the third-order optical nonlinearity shown by the films. Amongst the doped films, Sn0.92Eu0.08O2 films exhibited least optical limiting threshold. Graphical abstract: [Figure not available: see fulltext.]
