Holographic optical elements(HOEs)based on polymer composites have become a research hot spot in recent years for augmented reality(AR)due to the significant improvement of optical performance,dynamic range,ease of processing and high yield ***,it remains a formidable challenge to obtain a large field of view(FOV)and brightness due to the limited refractive index ***,we report an effective method to tackle the challenge by doping an epoxy liquid crystal termed E6M,which enables a large refractive index modulation of 0.050@633 nm and low haze of 5.0%at a doping concentration of 5 wt%.This achievement may be ascribed to the improved molecular ordering of liquid crystals within the holographic polymer *** high refractive index modulation can endow transmission-type holographic polymer composites with a high diffraction efficiency of 96.2%at a small thickness of 5μm,which would promise the design of thin and lightweight AR devices.

The use of transition metal-activated peroxymonosulfate（PMS） as an advanced oxidation technology has gained recognition. This study developed a catalyst using cobaltDlanthanum bimetallic oxide supported on layered molybdenum disulfide （Mo S2） as a carrier. The CoDLa/Mo S2catalyst was synthesised through coprecipitation, followed by calcination with an optimised metal ratio of Co:La=2:1 to activate PMS and degrade trace chloramphenicol（CAP） in water. The chemical composition of the catalyst was confirmed using X-ray diffraction （XRD） and X-ray photoelectron spectroscopy （XPS）. At catalyst and PMS dosages of 0.1 and 0.5 g·L-1, respectively, the degradation rate of CAP was 95% with in 30 min. The catalyst exhibitedstrong resistance to most interfering anions and maintained a high degradation rate at p H 3D11. Liquid chromatographyDmass spectrometry analysis revealed the potential degradation pathways of CAP in the CoDLa/Mo S2（2:1）/PMS system. For other pollutants, such as oxytetracycline,complete degradation was achieved within 20 min,demonstrating the broad applicability of the CoDLa/Mo S2（2:1）/PMS system for the degradation and removal of antibiotic organic contaminants. This study offers a feasible approach for the degradation of antibiotic organic pollutants, including CAP, in natural water bodies.
