We have investigated novel poly(p-phenylene vinylene) (PPV) derivative based organic light emitting diodes (OLEDs). We have used poly(2,3-diphenyl-1,4-phenylenevinylene) (DP-PPV) as an emitter in which an inorganic core of polyhedral oligomeric silsesquioxanes (POSS) have been incorporated. The hybrid structure obtained shows an improvement on the stability and an enhancement of electroluminescence properties. Charge-based deep level transient spectroscopy (Q-DLTS) has been used to study the…

Determination of traps in poly(p-phenylene vinylene) light emitting diodes by charge-based deep level transient spectroscopy
Charge-based deep level transient spectroscopy has been used to study the defect states that exist within poly(p-phenylene vinylene) (PPV), a semiconducting polymer with a band gap of about 2.4 eV.
Stabilization of Semiconducting Polymers with Silsesquioxane
Polyhedral oligomeric silsesquioxanes (POSS) anchored to poly(2‐methoxy‐5‐(2‐ethylhexyloxy)‐1.4‐phenylenevinylene) (MEH‐PPV) (MEH‐PPV–POSS), and to poly(9,9‐dihexylfluorenyl‐2,7‐diyl) (PFO)
Light-emitting diodes based on conjugated polymers
CONJUGATED polymers are organic semiconductors, the semiconducting behaviour being associated with the π molecular orbitals delocalized along the polymer chain. Their main advantage over
Light-emitting diodes based on poly-p-phenylene-vinylene: II. Impedance spectroscopy
Electrical impedance measurements on poly-p-phenylene-vinylene (PPV) light-emitting diodes in the frequency range between 100 Hz and 10 MHz are reported. A significant difference can be revealed
Relationship between electroluminescence and current transport in organic heterojunction light‐emitting devices
We measure the current–voltage and electroluminescencecharacteristics of single‐heterojunction, vacuum‐deposited organic light‐emitting devices(OLEDs) over a wide range of materials, temperatures,
