Ruthenium(II) complex as a phosphorescent dopant for highly efficient red polymers light-emitting diodes

Article Abstract:

The photoluminescence and electro luminescence features of a Ru complex drugged semi-conductive polymer films are described. The results suggest that the meticulous designing of chemical and device structure and selection of proper host materials, light-emitting diodes with greater efficiencies can be achieved.

Emission of tris(2,2'-bipyridine)ruthenium(II) by coreactant electrogenerated chemiluminescence: From O2-insensitive to highly O2-sensitive

Article Abstract:

The influence of dissolved oxygen on the emission of Ru(bpy)3(super 2+) is described by electrogenerated chemiluminescene (ECL) with tertiary amine as coreactant in aqueous solutions. The significance of the reactions between molecular oxygen and the ECL intermediate reducing radicals is demonstrated.

Electric-field-induced spin accumulation in polymer light-emitting diodes

Article Abstract:

The electric-field induced spin accumulation in polymer Light Emitting Diodes (LEDs) is demonstrated. Results show that, in a conventional polymer LED the applied electric field drives carriers with opposite spin signs moving along opposite directions apart from inducing generation of spin carriers.
