Abstract

A new wide viewing angle liquid crystal device was developed using PET technology.The liquid crystal molecule was twisted by double electric field.The rising time of the design with negative liquid crystal is slightly greater than the positive's,and the falling time is accordance with the positive liquid crystal.Compared with positive liquid crystal,the transmittance is increased about 10%.The relationship of transmittance with response time and voltage,was analyzed in the effect of three electrodes.The wide viewing angle technology monopoly of FFS and IPS was effectively solved.

Abstract

Pr3+-doped 12CaO·7Al2O3(C12A7∶Pr3+) powders were prepared using the coprecipitation method and were characterized by XRD,excitation and emission spectra,fluorescence lifetime,afterglow decay,thermoluminescence and photostimulated luminescence.The emission peaks at 491,535,614 nm are attributed to the transition of 3P0→3H4,3P0→3H5 and 1D2→3H4 of Pr3+ ions.The long afterglow emission locate at 491,535,614 nm,the time of the afterglow emission is about 300 s.By fitting the thermoluminescence spectrum data,the depth of the trap is about 0.63 eV.After the samples were irradiated by UV light(230 nm) for 5 min and placed in the dark for 5 min to drain the afterglow,the intensive photostimulated luminescence(PSL)is observed under infrared excitation(808 nm) due to the existence of the shallow traps.Our results indicate that C12A7∶Pr3+ phosphor with three-wavelength phosphorescence and two-wavelength optical storage can be used in optical storage field as one kind of multi-dimension recording materials.
