FIELD: chemistry.
SUBSTANCE: invention relates to a method for laser-induced modification of the chemical composition of transition metal dichalcogenide nanoparticles during their femtosecond laser ablation/fragmentation. Technically, formation of a new phase of molybdenum suboxide MoSxO3-x and molybdenum oxide MoO3 in the process of laser ablation/fragmentation is possible by replacing sulphur in MoS2 compound with oxygen, which is released from the solvent and distributed in the volume of the nanoparticle during its formation when exposed to femtosecond laser pulses onto the solution.
EFFECT: production of nanoparticles of molybdenum suboxides MoSxO3-x and molybdenum oxide MoO3 with controlled size and chemical composition in the process of femtosecond laser ablation/fragmentation of the original target of molybdenum disulphide 2H-MoS2 in ethanol.
