The linear and nonlinear optical properties of thin MoS2 layers exfoliated on an Au/SiO2 substrate were investigated both numerically and experimentally. It was found that the MoS2 layers with different thicknesses exhibited different colors on the gold film. The reflection spectra of the MoS2 layers with different thicknesses were calculated by using the finite-difference time-domain technique...

Introduction: Optical properties of different resin composites may affect the correspondence between tooth color and its structure. Therefore, this study aimed to evaluate and compare the optical properties of 8 commercial composite resin materials with 1 and 2 mm thicknesses. Methods: 32 resin composite disks with 10 mm diameter and 1 and 2 mm thicknesses were prepared. Color parameters of th...
