High-throughput synthesis of inorganic materials by laser irradiation

Developing innovative thin films is crucial for various applications but is still an experimental challenge. In this presentation, we will focus on the development of a new high-throughput synthesis methodology of high crystallization temperature materials such as refractory luminescent oxides. Experimentally, this methodology is a two-step method consisting of the deposition of a poorly crystallized layer on a substrate, followed by its ultra-fast crystallization induced by laser irradiation. The high quantity of generated data could be used to build a database to take advantage of machine learning tools in order to accelerate the optimization of the thin films properties. This annealing method allows to use extremely rapid heating ramp on a localized area enabling the screening of multiple laser parameters on the same substrate.
