The phosphors exhibit improved emission characteristics and very low residual emission (i.e. very low emission after the latent images are erased) and hence the phosphors improve the quality of radiog. 13708-63-9 and 13569-80-7 are just another two chemicals used in this study. images. .

Electroluminescence of silicon oxide (SiOx)-LnF3 thin films

Electroluminescence of silicon oxide (SiOx)-LnF3 thin films. Vlasenko, N. A.; Denisova, Z. L.; Khomchenko, V. S. (Inst. Semicond., Kiev 252 650, USSR). Phys. Status Solidi A, 81(2), 657-60 (English) 1984. CODEN: PSSABA. ISSN: 0031-8965. DOCUMENT TYPE: Journal CA Section: 73 (Optical, Electron, and Mass Spectroscopy and Other Related Properties) The characteristics of the electroluminescence (EL) 1st obsd. in SiOx-LnF3 films are reported. Ln dopants such as Tb, Eu, Sm, Tm, Dy were used. The EL films were deposited by vacuum evapn.; their thickness was 0.3 - 1 mm. There were no dielec. layers between the EL films and electrodes (In2O3 and Al). The emission spectra show a series of broad lines which are typical for Ln3+ ions. The highest brightness (u103 cd/m2 at 300 K) was obtained with TbF3 doped films. 13765-25-8 and 13708-63-9 which are cas registry numbers of substances are two of reagents here. From an anal. of EL and elec. characteristics, it is concluded that the EL mechanism is an impact excitation of Ln3+ ions or the LnF3 complexes. Electrons taking part in this process are injected from the electrodes, the injection mechanism at 300 K is the thermionic emission. .
