摘要：
The preparation and characterisation of an inorganic blue-emitting alternate-current electrolumenescent (ACEL) cell based upon ZnS:Tm, Li phosphor powder are described. Electroluminescent and photoluminescent spectra clearly show a dominant blue-emission band peaking at 2.6 eV (477 nm) originated from (1)G(4)-->H-3(6) transition, Advantages and drawbacks of the powder-based ACEL cell have been discussed in comparison with a ACEL thin-film based upon a similar material, The near-infra-red band (801 nm, 1.55 eV, F-3(4)-->H-3(6)) Seen in thin-film structure was significantly suppressed in these types of devices.
