In this study, AZO films are prepared with selective laser sintering (SLS) of AZO nanoparticles. A nanosecond pulsed laser was utilized to selectively sinter AZO nanoparticles with Al doping concentrations of 0.5 wt%, 1.0 wt%, and 2 wt% on quartz substrates. The laser process facilitated the melting and interconnection of the AZO nanoparticles, resulting in the formation of continuous thin films. Experimental results revealed that the carrier concentration in AZO films increased with higher laser intensity and greater pulse overlap ratios. The optimal thermoelectric performance was observed at a doping concentration of 0.5 wt%, achieving a power factor of 11.05 μW/mK2. This highlights the potential of AZO films for thermoelectric energy harvesting applications when processed via SLS.Aluminum-doped zinc oxide nanoparticlesPower factorSeebeck coefficientSelective laser sinteringThermoelectric filmsjournal article10.1016/j.ceramint.2025.05.408
