Abstract

In the face of increasing risks caused by high power lasers, nonlinear optical (NLO) materials like porphyrins (Por) have attracted interest because of their outstanding NLO properties. However, the performance of porphyrins is still far from practical application. Here, Carbon dots (CDs) and a series of porphyrins were combined to synthesize the Por-CDs nanohybrids. The nonlinear and photo physical of Por-CDs hybrid materials were investigated. The Por-CDs was confirmed by Fourier Infrared Spectroscopy (FT-IR), Fluorescence spectra and TEM. The nonlinear optical (NLO) performance of Por-CDs was evaluated by the Z-scan test. Nonlinearity present in Por-modified CDs. At same transmission intensity, the Por-CDs composites showed enhanced NLO properties in comparison to the Por and CDs. This research provides a promising route for the design of novel NLO materials.
