We have demonstrated that the compositional modification of the Ca/Ag films is principally responsible for a high transmittance (over 70% in the visible range) and low sheet resistance (10–12 Ω/sq). X-ray photoelectron spectroscopy (XPS) sputter d

The Rayleigh scattering (RS) by independent small particles is a well-known effect which also accounts for the blue color of the sky. Lately, the blue shift of the greenish emission band of thin films of Alq 3, tris(8-hydroxyquinoline)aluminum, after

We have fabricated top-emitting red electrophosphorescent organic light-emitting devices with the 4,4′-N,N′-dicarbazole-biphenyl (CBP): bis[2-(2′-benzothienyl)-pyridinato-N,C3′]iridium(acetylacetonate) (BtpIr(acac)) as a emitting layer. Emiss

Tris(8-hydroxyquinoline)aluminum (AlQ) powder has been characterized using photoluminescence and electron spin resonance (ESR). The broad asymmetric excitation band is centered at ∼425 nm, while the emission band centered at ∼505 nm is similar to

Doubly doped YVO 4 :Pb 2+ , Eu 3+ red phosphor materials with fixed Eu 3+ concentration (5 mol%) and varying Pb 2+ concentration were prepared via a self-propagating (combustion) synthesis. This consisted of bringing a saturated aqueous solution of t

Eu3+ activated CaSiO3, (Ca, Ba) SiO3 and (Ca, Sr) SiO3 have been prepared by sol-gel technique. Residual solvent and organic contents in the gel were removed by firing at 100°C for 3–4 h at 300 and 600°C for 2 h. Small exothermic shoulder around

Amorphous tris(8-hydroxyquinoline) aluminium (Alq3) thin films were deposited on fused silica substrates by thermal evaporation. Optical absorption, emission and excitation spectra were measured at room temperature and, for the first time, at 80 K, o
