AI Technical Summary

Technical Problem

In existing technologies, second-order nonlinear optical effects can only exist in non-centrosymmetric systems, and the preparation methods are complex, energy-intensive, have long reaction times, and require high reaction and purity, making it difficult to efficiently prepare materials with second-order nonlinear optical effects.

Method used

Lead-based perovskite material with the chemical formula (C10H11N3)PbBr4 was prepared by reacting it in an oil bath at 373–393 K for 3 hours using bis(4-pyridine)amine and lead bromide as raw materials and adding hydrobromic acid as solvent, thus producing a lead-based perovskite material with a monoclinic crystal system and Cc space group.

Benefits of technology

A lead-based perovskite material with strong second-order nonlinear optical effects was prepared by achieving simple operation, low energy consumption, short reaction time, and low requirements for reaction and purity. The second harmonic response intensity reached 4.2 times that of commercial KDP materials.
