Description
| - The electroluminescence (EL) characteristics of ZnS:Mn doped with KCl for alternating current thin film electroluminescent devices deposited by a RF sputter system from ZnS and Mn targets are investigated. Measurement of EL brightness and luminous efficiency was carried out. K is uniformly distributed through the 1 micrometer ZnS film after 5 minutes anneals at T > 600 degreeC, while Cl requires an anneal at T > 700 degreeC before diffusion results in a uniform concentration. Upon annealing at 700 degreeC for 5 minutes, the equiaxed grains were consumed by growth of the columnar grains, and growth of the columnar grain diameter is enhanced by the presence of KCl. The mixed cubic and hexagonal atomic stacking observed in as-deposited films became more cubic upon annealing with KCl co-dopants. K+ diffuses by an interstitial mechanism and it occupies an interstitial site in the cubic structure where it acts as a donor, similar to substitutional Cl- ZnS:Mn co-doped with KCl shows significant improvement

- V článku jsou zkoumány elektorluminiscenční vlastnosti (EL) ZnS:Mn dotovaného KCl pro ACTFEL zařízení. Byl měřen jas a světelná účinnost pro různé doby dotování pomocí RF naprašování a různé koncentrace KCl. Bylo ukázáno, že objemový materiál ZnS:Mn dotovaný KCl vykazuje mnohem lepší EL jas a světelnou účinnost. To je způsobeno lepší krystaličností a modifikací bodových defektů a objemového náboje v tenké vrstvě ZnS:Mn + KCl. (cs)
