The polymer dispersed liquid crystals(PDLCs) doped with neodymium oxide(Nd 2O 3) nanoparticles were prepared.The electro-optic characteristics from 320 nm to 400 nm were tested.The results show that the electro-optic switching characteristics in UV region can be effectively achieved.The strong absorption in UV region increases from 320-325 nm to 320-340 nm.The second absorption band appears near 365 nm,and the band width gradually becomes narrow with voltage rising.The absorption peak moves towa...
