• Fluorine material MgF2 with Zn has recently been reported to have good encapsulation properties with high optical transmittance. We fabricated a 200 nm Mg--Zn--F passivation film for encapsulation of organic light emitting diodes using a radio frequency magnetron sputter. The water vapor transmission rate of Mg--Zn--F passivation film on poly(ethylene naphthalate) was determined using a calcium degradation test. Heating of the substrate during sputtering enhanced the device performance, and Mg--Zn--F film applied to a polymer light emitting diode device almost doubled its operating lifetime.
