Gain enhancement of perovskite nanosheets by a patterned waveguide: excitation and temperature dependence of gain saturation
Abstract Optical gain enhancement of two-dimensional CsPbBr3 nanosheets was studied when the amplified spontaneous emission is guided by a patterned structure of polyurethane-acrylate. Given the uncertainties and pitfalls in retrieving a gain coefficient from the variable stripe length method, a gai...
