Photo- and electroluminescent properties europium complexes using bistriazole ligands
Luminescent properties of two heteroleptic dibenzoylmethanate europium(III) complexes with 1,3-bis(5-pyridin-2-yl-1,2,4-triazol-3-yl)propane (H2L1) and 1,4-bis(5-pyridin-2-yl-1,2,4-triazol-3-yl)butane (H2L2) as ancillary ligands are described. The two double-layer-type electroluminescent cells with the structures: (1) ITO/NPB(40 nm)/Eu(DBM)2HL1 (40 nm)/LiF (1 nm)/Al (100 nm) and (2) ITO/NPB(40 ...
متن کاملHigh luminance and efficient GaN:Eu inorganic EL devices for monochromatic display applications
In this paper we report GaN:Eu AC-TDEL devices with high luminance and high efficiency levels obtained through optimized phosphor growth techniques and device structure. The GaN:Eu phosphor is grown using interrupted growth epitaxy (IGETM ). An improved thick dielectric layer for inorganic electroluminescent EL display devices has been achieved through a composite high-κ dielectric sol-gel/powd...
متن کاملContrast-Enhancement in Black Dielectric Electroluminescent Devices
A high contrast electroluminescent (EL) device structure is presented. The diffuse luminous reflectivity from the metal/dielectric/phosphor/indium-tin-oxide/glass EL device structure is 3%. A Eu-doped GaN phosphor is used to demonstrate the contrast-enhanced operation. Low reflectivity is achieved by inserting a light-absorbing black thick-film BaTiO3 layer between the phosphor and the rear met...
متن کاملSolid-state electroluminescent devices based on transition metal complexes.
Transition metal complexes have emerged as promising candidates for applications in solid-state electroluminescent devices. These materials serve as multifunctional chromophores, into which electrons and holes can be injected, migrate and recombine to produce light emission. Their device characteristics are dominated by the presence of mobile ions that redistribute under an applied field and as...
