Abstract

In this work, we proposed a fluorescence conversion layer with polarization characteristics to enhance UV polarization detection for the first time. To achieve this goal, the colloidal lead halide CsPbBr3nanowires (NWs) with appropriate lengths were synthesized by the method of ultrasonication synthesis assisted by the addition of hydrobromic acid (HBr) ligands. By adding HBr, the properties of synthesized NWs are improved, and due to the controllable perovskite-stretched NWs, polymer composite films were fabricated, which can generate photoluminescence (PL) with strong polarization. The optimized stretched composite film can achieve a polarization degree of 0.42 and dichroism ratio (I∥/I⊥) of 2.49 at 520 nm. Based on this film, an imaging system with polarization-selective properties and efficient UV spectral conversion was developed. The spectrum conversion of 266 to 520 nm luminescence wavelength was realized and sensitive to the polarization of incoming 266 nm UV light. The experimental results also showed that the response after spectral conversion is greatly improved, and different responsivities can correspond to different polarization states. This imaging system overcomes the insufficiency of the conventional charge coupled device (CCD), which makes it difficult to receive the optical signal for high-quality UV imaging. The use of light conversion films with polarization characteristics for polarized UV imaging is of great significance for improving the detection of solar-blind UV bands and the recognition of military targets.
