A novel electrochromic device with three optical states, transparent, specular mirror, and black, is demonstrated. The cell is constructed by sandwiching gel electrolyte containing silver nitrate between one flat and one particle-modified indium thin oxide electrode. The optical states can be switched by altering the potential across the two electrodes. All changes are reversible and show good stability over 2500 cycles of testing.

An AC voltage-driven electrochemiluminescent (ECL) device containing a ruthenium(II) complex as luminescent species was fabricated, and advantages of the AC-driven method such as electrochemical and emission response were studied. The cell can be easily fabricated by simply placing the emitting solution between electrodes. The emission turn-on response time and emission intensity were dramatically improved by introducing the AC method. The turn-on response time was speeded up by increasing applied frequency. 4 ms was achieved at 200 Hz, which was much faster than the DC method (1.5 s). The current efficiency for the emission was estimated to be 0.59 cd A−1. The mechanism of the improved ECL properties was discussed from a viewpoint of electrochemical reaction.

We have demonstrated electroswitchable emission and coloration using a novel composite material containing luminescent europium(III) complex Eu(hfa)3(H2O)2 and diheptyl viologen HV2+. The photoluminescence of the Eu(III) complex was controlled by the electrochemical coloration of HV2+via intermolecular energy transfer mechanisms.
