Electroluminescence of Zn2GeO4:Mn through SiC whisker electric field enhancement

Alternating current (AC) electroluminescence of thin film oxide phosphors is well known. However in this work electroluminescence of bulk oxide powder phosphors is achieved. A new type of AC Electroluminescent (ACEL) device has been created and developed by integrating SiC whiskers into a phosphor matrix composed of manganese-activated zinc germanate (Zn2GeO4:Mn2+). The conductive SiC whiskers enhance the average electric field in specific …
