Development of the photorefractive (PR) polymer sensitive to the near infra-red region have been required to realize the non-destructive image processing of the living tissue. In this study, a PR polymer with the perovskite(PVK) particles, which generally absorbs NIR light, was fabricated for the first time using the in-situ grown method. The PR properties by the transient photocurrent measurement and the degenerate four wave mixing measurement were performed with the PR polymers; the PR polymer sensitized with PVK or with PCBM, and without sensitizer. As results, it showed the equivalent performance to well-used PCBM sensitized PR polymers. These results show that the PVK particles can be a promising candidate for the NIR sensitizer in PR polymer.
