Study of second-order nonlinear optical properties in lead-free double perovskite csaginbicl - afosr/IOS (SOARD) international science

The Air Force Office of Scientific Research (AFOSR) awarded $100,000 under the Air Force Defense Research Sciences Program (CFDA 12.800) to Instituto De Fisica De SAO Carlos, a Brazilian state-controlled research institution, to conduct a three-year project spanning September 30, 2025, through September 29, 2028. The primary deliverable is fundamental and applied scientific research investigating second-order nonlinear optical properties in lead-free double perovskite cesium silver indium bismuth chloride (CsAgInBiCl) materials. This research directly supports the Air Force's strategic objective to maintain technological superiority and prevent technological surprise in materials science and advanced optics relevant to Department of the Air Force mission capabilities.

As an international collaborative initiative under the AFOSR International Science program, the award leverages Instituto De Fisica De SAO Carlos' established expertise in nonlinear optics and advanced materials research to contribute to the development of next-generation optical materials with potential applications in defense-related photonic systems. The research outcomes—including scientific publications, experimental data, and technical findings on lead-free perovskite optical properties—will inform broader Air Force efforts in materials innovation while strengthening international research partnerships within the Defense Research Sciences Program framework.
