Layered transition metal dichalcogenides with excellent nonlinear absorption properties have shown remarkable performance in acting as ultrafast photonics devices. In our work, palladium diselenide (PdSe ) nanosheets with competitive advantages of wide tunable bandgap, unique puckered pentagonal str...
