“…Meanwhile, the transmission spectrum of another identical sample treated only by photobleaching was also detected. As shown in Figure , the sample exhibits a strong absorption band around 500 nm before exposure, owing to the utilization of the green-sensitive BTCP as photosensitizer. , After flood photobleaching, the two samples, with and without transmission VHG, exhibit remarkably high transparency, and their total transmittance values within the visible light range of 400–800 nm both exceed 96.21%. Meanwhile, the η of the reflection grating increased to 98.8% after UV bleaching.…”

The refractive index modulation (Δn) of photopolymers is a key performance indicator in determining their application potentials in holographic optical elements (HOEs). In this study, four fluoroelastomers (HT-HS, HT-F185, HT-L80, and HT-F197) containing hydroxyl groups as active functional groups are selected to construct low refractive index host matrices with isocyanates. Through a combination of them with high refractive index monomers, a series of transparent photopolymers are obtained. Among them, one containing 16 wt % HT-F197 has the highest sensitivity, which can record a transmission volume holographic grating (VHG) with high resolution (3600 lines/mm) and diffraction efficiency (95.76%) under exposure of a 532 nm laser. Its Δn is up to 0.054. Furthermore, a reflection VHG with high performance (4900 lines/mm resolution and 92.32% diffraction efficiency) can also be achieved. After photobleaching, its transmittance within 400−800 nm reaches 96.21%, showing great potential in the fabrication of transparent HOEs.
