In the past two decades there has been increasing interest in the nonlinear optical absorptive properties of nanostructures zero-dimensional one-dimensional 1D two-dimensional 2D because of their uniq

In the last twenty years, there has been a growing fascination with the nonlinear optical absorption characteristics of nanostructures (zero-dimensional, one-dimensional (1D), two-dimensional (2D)) due to their distinct optical properties and their potential applications as saturable absorbers and optical limiters.
