Abstract

The optical limiting performances of few-layer transitional metal dichalcogenides (TMDs) nanosheets in the VB group (

{VS}_{2}

{VSe}_{2}

{NbS}_{2}

{NbSe}_{2}

{TaS}_{2}

, and

{TaSe}_{2}

) were systematically investigated for the first time, to the best of our knowledge. It was found that these TMDs nanosheets showed a normalized transmittance in the range of 20%–40% at the input energy of
