Single‐crystal TiS 2 nanosheets with very uniform morphology and narrow size distribution were prepared via a modified colloidal chemistry method by Haibo Zeng, Shixiang Xu, Han Zhang and co‐workers (article number 1701166 ). The TiS 2 nanosheets were calculated to have direct‐bandgap structure and showed remarkable nonlinear optics property. A TiS 2 nanosheets‐based saturable absorber can be developed as an excellent candidate for photonic devices.
