The nonlinear absorption of Ti3C2 quantum dots (QDs), Ag nanoparticles and Ti3C2 QDs-Ag nanocomposites were studied by using nanosecond Z-scan technique. It was found that, Ti3C2 QDs and Ag nanoparticles exhibit saturation absorption (SA), while the Ti3C2 QDs-Ag nanocomposites can exhibit SA or reverse saturation absorption (RSA) depending laser intensity. The investigation indicates that adding of Ag nanoparticles can regulate the nonlinear absorption of Ti3C2 QDs, even make it change from SA to RSA. The origin of nonlinear absorption and transformation was also analyzed and discussed in terms of plasmon bleaching.

Active accounts were imported to the new platform and assigned a random password by default. In order to access your account you need to access the login page and go through the Lost Password dialog (involves the system sending you an email with instructions) in order to reset your password. This step is necessary as passwords are kept in hashed form and the new platform uses modern hashing algorithms incompatible with the previous ones.
