Strong green electroluminescence from silicon based oxide films

Photoluminescence and electroluminescence of amorphous SiOx films prepared by reactive evaporation of silicon with oxygen

“…The electric field was greater than 7 · 10 6 MV/cm. A rather strong green EL located at 510 nm was also observed by Wu et al [9] for sputtered SiO 2 films containing Ge, Si or Al. The EL was attributed to luminescence centers present in the films.…”
