Research abstract
THE FEASIBILITY OF LASER ANNEALING ZNS:MN AND SRS:CEF3 THIN FILM ELECTROLUMINESCENT (TFEL) PHOSPHORS IS EXAMINED. ZNS: MN IS THE LIGHT-EMITTING LAYER USED IN COMMERCIAL EL DISPLAYS. THE LASER ANNEALING TECHNIQUE HOLDS PROMISE FOR IMPROVING THE BRIGHTNESS OF THESE DEVICES, WHILE ALSO HAVINGPOTENTIAL AS A MORE EFFICIENT EL PANEL PROCESSING METHOD. RARE EARTH DOPED ALKALINE EARTH SULFIDES ARE A NEW CLASS OF THIN FILM PHOSPHORS BEING INVESTIGATED FOR MULTICOLOR EL DISPLAYS. LASER ANNEALING MAY BE THE MOST VIABLE METHOD FOR PROVIDING THE HIGH ACTIVATION TEMPERATURES REQUIRED FOR THESE MATERIALS. THE MAJOR PROGRAM OBJECTIVES ARE: 1. DETERMINE IF LASER ANNEALING OF ZNS:MN AND SRS:CEF3 CAN IMPROVE BRIGHTNESS AND EFFICIENCY OF EL DEVICES.
