초록
Surface light-emitting transparent nanocellulose papers operating by alternating current voltages were demonstrated, where phosphors were embedded in the paper and silver nanowire electrodes were formed on both side of the paper. Silver nanowire electrodes were first coated on membrane filter with vacuum filtration using wet wiper tissues and then successfully transferred to the paper surface by a mechanical compression. The power consumption of a light-emitting paper was small in less than 0.36혻W/cm2. We could control the luminescent color and intensity from light-emitting papers by adjusting electrical frequency and the applied voltage level. White light emission was also demonstrated by using phosphors with a broad luminescence spectrum. The results develop into a versatile approach for commercializing the nanofibrillated cellulose and pave the way towards the realization of commercially viable, flexible and transparent light-emitting papers.
