Templated deposition of MoS2 nanotubules using single source precursor and studies of their optical limiting properties.

We demonstrate a simple way of fabricating bulk quantities of molybdenum disulfide (MoS2) porous nanotubules (NTs) by templated deposition from a single source precursor based on tetrakis(diethylaminodithiocarbomato)molybdate(IV). Bulk quantities of crystalline MoS2 NTs that consist of agglomerates of nested nanocapsules were obtained by this one-step evaporation method. We found that MoS2 NTs show good optical limiting behavior with 532-and 1064-nm nanosecond laser pulses, and the size-effect of the NTs on optical transmission was observed.
