| Research Abstract |
We have successfully synthesized rare earth metal ion doped Perovskite type metal oxide nanophosphor via hydrothermal reaction under supercritical water conditions. The size of the particles obtained was in the range from 20 to 40 nm. The quantum efficiency of the nanophosphors was 12 % being comparable to that of bulk materials. The prototype dispersion electroluminescence (EL) element used the nanophosphors obtained showed the typical electroluminescence behaviors under an electric field of 350 V at 1 kHz. Furthermore, EL was observed under an electric field of low voltages by depressing the thickness of the dispersion layer to around 10 micron meter. These results show that metal oxide nanophosphors can be applicable to a novel dispersion electroluminescence device.
