We report a thin film electroluminescent device with a three-layer structure （diamond/CeF3/SiO2 films）, which has a luminance of 1.5 cd/m^2 at dc voltage 215 V. The electroluminescence spectrum at room temperature shows that the main peaks locate at 527 and 593nm, which are attributed to isolated emission centers of Ce^3＋ ions. 相似文献

This paper reports that bunchy flake-like nano-graphite crystallite
films (BNGCFs) were deposited on Si substrates by using the microwave
chemical vapour deposition technique. Furthermore the BNGCFs were
characterized by x-ray diffraction spectra, scanning electron
microscopy, Raman spectra and field emission (FE) I--V
measurements, and a lowest turn-on field of 1.5V/μm, and a high
average emission current density of 30mA/cm* 相似文献
