Cathodoluminescent characteristics and light technical parameters of thin-film screens based on oxides and oxysulfides of rare-earth elements

Multicolor Depth-Resolved Cathodoluminescence from Eu-Doped SiOC Thin Films

“…The same working principle also operates in field-emission lamps (FELs), which attract considerable interest as mercury-free, efficient light sources. 3 Although it is true that in FED and FEL technologies many efforts are currently devoted to the development and optimization of the electron emitters, there are still very important issues related with phosphor properties, including the synthesis of thin-film phosphors exhibiting a full visible luminescence spectrum 4 and the matching of different luminescent layers for development of new principles of color variation. 5 Most of the phosphors used in FEDs are rare earth (RE)-doped oxides or sulfides; among all the available REs, a particular interest is devoted to Eu, owing to its characteristic to be stable both in its divalent and trivalent oxidation state.…”

“…Among the many problems connected with development of flat-panel displays, there are two very important issues: creation of thin-film phosphors with a full spectrum of luminescence 1) and matching of different luminescent layers with each other and with other layers for development of new principles of color variation. 2) Technological compatibility of luminescent materials together with op-WLPDO# OLJKW# HPLVVLRQ# SDUDPHWHUV# +khORU/# EULJKWQHVV etc.)…”
