Degradation of OLED performance by exposure to UV irradiation

This paper reports the influence of UV radiation on the interface of a co-deposited EIL and Ag : Mg (10 : 1) cathode unit and pixel shrinkage.

A Field Emission Light Source Using Reflective Metal Groove Anode and Long Narrow Stripe Cathode

A novel reflective metal anode with different groove structures and a set of parallel long narrow stripe Carbon nanotube (CNT) cathodes to fabricate a 7 inches field emission backlight unit (CNT-FEBLU) has been carried out in this paper. In comparison with a simple diode structure, which has the same stripe cathode unit with screen printing phosphor layer on ITO glass surface as the anode, the reflective metal anode has some advantages such as sustaining high field emission current, no unexpected arcing, and high illumination and uniformity without phosphor degradation. The results show that a reflective metal anode not only conducts the residual charges and heat from the phosphor surface effectively, but also reflects the light to one side of the panel through the cathode end and exhibits high illumination without obvious obstacle by the narrow stripe cathodes. The luminance of the reflective metal groove anode we proposed is 11530 cd/m2, with the emission current density of 1.52 mA/cm2 under the electric field about 1.07 V/μm.

Development of the Two-Stage Planar Fem for the Terahertz Band on the Basis of the ELMI Accelerator

Project of the two-stage FEM-generator based on the ELMI accelerator with two parallel sheet electron beams formed in a single cathode unit is under development currently. In this scheme the first beam is used in the low-frequency section of the FEM for generating of high-power 75 GHz radiation. This radiation than goes through the coupling waveguides to the second channel and operates as a pumping wave which scatter on the second beam into the terahertz band. Our paper is devoted to modeling of various stimulated scattering regimes in this high-frequency section. Regime of the selfamplified spontaneous emission (SASE) is considered as well as a generator with resonator for the scattered radiation formed with advanced Bragg structures, based on coupling of traveling and quasi-critical waves
