    Near-field investigation of ZnS:Mn nanocrystal phosphors in thin-film electroluminescent device

  • Original language description

    A study of the luminescence characteristics of nanostructured ZnS:Mn ACTFEL devices is presented. Nanocrystal ZnS:Mn phosphor has been prepared by sol method using inorganic materials at room temperature. The nanocrystal of ZnS:Mn has cubic crystal structure with average 3 nm of particle size, emitting bright orange light at peak wavelength 585-595 nm with the full width of half maximum 90 nm under UV 337 nm excitation, and the brightness as high as the corresponding bulk pure cubic ZnS:Mn phosphor. Incomparison with the bulk ZnS:Mn phosphor these nanocrystals have clearly high luminescent efficiency with its luminescent decay time at least 5 orders of magnitude faster. It means that the oscillator intensity of luminescent centers in ZnS:Mn nanocrystal enhances at least 5 orders of magnitude than that in corresponding bulk ZnS:Mn. The local measurement of this luminescent efficiency by Scanning near-field optical microscope allows discover a hot luminescence in these nanocrystals.

    Výzkum tenkovrstvých luminoforů s ZnS:Mn nanokrystaly vpomocí metody blízkého pole

  • Czech description

    Článek přináší studii luminiscenčních vlastností nanostrukturovaných ZnS:Mn ACTFEL. Jsou specifikovány rozměry nanokrystalů, který po ozáření UV světlem 337 nm vyzařuje maximum v oblasti 585-595 nm. Tyto nanokrystaly vykazují podstatně vyšší světelnou účinnost než objemový materiál. Lokální měření luminiscenční účinnosti pomocí SNOM umožní lokalizovat místa horké luminiscence v těchto krystalech.
