Effects on Light Efficiency in Discharge and Solid-State Lighting Operation, Supplied by No-Sinusoidal Voltage
(Ieee-inst Electrical Electronics Engineers Inc, 2016-05-01)
The widespread use of discharge lamps and solid-state lighting is justified by its high-energy efficiency. However, the massive use causes degradation of power quality provided. In this context, the objective was the ...
Low voltage electroluminescence of terbium- and thulium-doped zinc oxide films
(Elsevier B.V., 2006-07-20)
Strong interest in developing technology for visual information. stimulates research for thin film electroluminescent devices. Here, for the first time, we report that thulium- and terbium-doped zinc-oxide films are suitable ...

UV-Ozone Generation from Modified High Intensity Discharge Mercury Vapor Lamps for Treatment of Indium Tin Oxide Films
(TAYLOR & FRANCIS INCPHILADELPHIA, 2012)
In a homemade UV-Ozone generator, different ignition tubes extracted from HID mercury vapor lamps were investigated, namely: 80, 125, 250 and 400 watts. The performance of the generator in function of the type of the ...
White light emitting devices by doping polyfluorene with two red emitters
(ElsevierLausanne, 2013-02)
The photo and electroluminescent properties of a single-layer multi-component blend composed of only blue and red emitters were studied. The blue emitter poly(9,9-dihexyl-2,7-fluorene)] (LaPPS10) was used as the matrix, ...
Effect of ion concentration of ionomer in electron injection layer of polymer light-emitting devices
(Elsevier B.V., 2006-06-15)
Polymer light-emitting devices (PLEDs) with poly(2-methoxy-5-hexyloxy)-p-phenylenevinylene (OC1OC6-PPV) as the emissive layer were studied with an electron injection layer of ionomers consisting of copolymers of styrene ...
