PROPERTIES OF ZNS THIN-FILMS PREPARED BY 248-NM PULSED-LASER DEPOSITION

Pulsed laser deposition (PLD) from a hot pressed manganese doped ZnS t arget using a KrF laser, has produced a high rate deposition method fo r growing luminescent thin films. Good stoichiometric quality and typi cal luminescent crystal structures have been observed with a predomina nt hexagonal phase and little evidence of the cubic phase. The lumines cent characteristics were determined by cathodoluminescence and photol uminescence excitation and stable electroluminescence was observed und er pulsed dc conditions with a minimum brightness of 150 cd/m2. PLD fi lm characteristics are compared with those observed in radio-frequency sputtered samples.
