Abstract: The structural evolution of tin dioxide (SnO₂) nanoparticle films during resonant laser sintering is investigated using simultaneous, time-resolved small-angle (SAXS) and wide-angle (WAXS) X-ray scattering combined with high-speed near-infrared (NIR) thermography. A focused synchrotron X-ray beam enables spatially and temporally resolved probing of structural changes at both the microstructural and crystal structure scale. The evolution of the temperature field is monitored to correlate the structural dynamics with the temperature–time profile and to analyze the grain growth kinetics. The structural changes observed ${in}$ ${situ}$ are complemented by ${ex}$ ${situ}$ scanning electron microscopy (SEM) of the evolved microstructure. In addition, the lattice expansion by laser induced heating is determined, and the corresponding thermal expansion coefficients are derived. These space- and time-resolved measurements provide detailed insights into the mechanisms governing resonant laser sintering of SnO₂ nanoparticles.
