The cation density at the interface of a transparent anode and an organic layer has been measured for several hole transport (HT) materials. The number of cations at the interface of ITO:MoOx with rubrene, NPB, m-MTDATA and TCTA was found to range fr

We use charge modulation spectroscopy (CMS) in model holes-only devices to address the reason for decreasing quantum efficiency with increasing drive current in organic light-emitting diodes based on Alq3 doped with the red dye DCJTB. We are able to

Silver iodide micro and nanocrystals were synthesized and examined with a variety of luminescence techniques at low temperatures. The donor-acceptor nature of the recombination luminescence peaking around 2.78 eV in bulk AgI was confirmed. The peak o

A review of quantum confinement effects in nanocrystals of silver bromide (AgBr) and silver iodide (AgI) is presented. AgBr is an indirect gap semiconductor while AgI has a direct band-to-band lowest energy transition. An examination of the low-tempe

The visible emission and excitation spectra of AgBr microcrystals containing single and parallel double twin planes has been obtained. A band at 462.28 nm (2.6813 eV) is observed in the excitation spectrum. This feature is about 2.5 meV below the ind

Using a modified reverse micelle protocol with acetyl bromide as the bromide source, AgBr nanocrystals can be grown over a size range from 30 A radius to bulk. These clusters exhibit quantum confinement indicated by an increasing blue shift of the fr

The electroluminescence quantum efficiency of organic light-emitting diodes with a doped Alq [tris(8-quinolinolato)aluminum] emitting layer is found to decrease markedly with increasing current density. This phenomenon was investigated using multilay
