Özet
In this study, nonlinear optical (NLO) properties of CsPb(Cl/Br)<inf>3</inf> perovskite quantum dots (PQDs) and Zn doped CsPb(Cl/Br)<inf>3</inf> PQDs was systematically investigated, discovering its potential for advanced NLO devices. Initially samples were synthesized and characterised using UV-Vis, photoluminescence (PL), and TEM method. Next, open and closed aperture Z-scan experiments and optical limiting evaluations were carried out under varying excitation conditions. We measured that nonlinear absorption (β), nonlinear refractive (n<inf>2</inf>) indices and third-order nonlinear susceptibility (χ<sup>3</sup>) for CsPb(Cl/Br)<inf>3</inf> PQDs to be on the orders of 10<sup>−11</sup> cm/W, 10<sup>−16</sup> cm<sup>2</sup>/W and 10<sup>−14</sup> esu, respectively. Interestingly, it has been observed that the NLO properties of Zn -doped samples beings prominent considerably compared to undoped samples, with the rate of increasing as the Zn content. The results show that CsPb(Cl/Br)<inf>3</inf> PQDs are remarkable material for applications on the next-generation NLO devices.
