Non linear effects in monomode ytterbium doped silica fibers : cooperative luminescence

We studied the visible fluorescence of two yb3+-doped fibres pumped by a CW titanium-sapphire laser in the infrared range (from 840 nm to 975 nm). The fibre # 1 (codoped with alumina) has a core of 2.1 pm diameter and is doped with about 600 ppm molar Yb203. The fibre # 2 (ccdoped with phosphorous) has a core of 3 pm diameter and is doped with about 85 ppm molar Yb203. The guided light output e...

Luminescence properties of Mn doped Zn2SiO4 phosphor films synthesized by combustion CVD

Zn2SiO4:Mn 2+ phosphor films were successfully prepared by a novel combustion chemical vapor deposition (CCVD) method. In the CCVD process, a flammable solution, containing precursor materials, is atomized and sprayed through a specially designed nozzle and ignited to form a combustion flame. This enables crystallized films to be directly deposited onto a substrate in open-atmosphere with no po...

Electroluminescence from Phosphor-doped nanocrystals

Alternating current thin-film electroluminescent (ACTFEL) devices already occupy a segment of the largearea, high-resolution, flat-panel-display market. The AC-TFEL displays, which consist of a phosphor layer, such as manganese doped-zinc sulfide (ZnS:Mn), vertically sandwiched between two insulators that are contacted by electrodes, are robust, possess long lifetimes, and offer high luminance ...
