The electroluminescent light source can be used as flexible compact flat sources of uniform illuminating. The studies on improvement of its main characteristics, especially of color intensity generation, continue. In the paper the possibility of using the changing capacitive and current characteristics of flexible light sources - electroluminescent panels to fix and determine the level of external radiation, which includes the near infrared, optical and ultraviolet ranges, has been shown. The degree of the influence of radiation on the capacitive and current characteristics of these structures based on ZnS: Cu, Mn phosphor using a barium titanate ferroelectric has been revealed. During the studies the instrumental and expert analysis as well as the non-destructive and destructive technological control have been used. It has been found that while changing the radiation intensity from 0 to 2500 kd/m the electric capacity of the structure with 600 cm area becomes 25 % increased, and the intensity increase leads to considerable proportional increase (up to 20 %) of the structure conductivity current
The secondary-emission multiplier of spatial-distributed flows of electrons – microchannel membrane – determines along with the photocathode, luminescent screen, electron-optical system determines the amplifying characteristics of the electron-optical transformers, photoelectronic multipliers. This, in its turn, determines the application areas and the operating range of the items. The actual task is an improvement of the microchannel membrane parameters and the search for new approaches to manufacture on alternative materials of the secondary-emission multipliers. In the paper the use of self-organizing high-ordered porous anode structures of aluminum oxide as the secondary-electronic emitters have been considered. The theoretical and practical approaches to development and the implementation of the computer models of processes of multiplying electrons in the channel of the based on aluminum oxide, have been offered. Based on the results of the calculations, performed using this model, the amplifying ability of such channels has been determined, their optimal caliber is 25, and the supply voltage is 300 V. A comparative analysis of these characteristics of secondary electron multipliers with corresponding parameters of microchannel plates based on lead silicate glass has been performed. It has been determined that that porous anodized alumina may be suitable for the manufacture of secondary electron multipliers. Its secondary emission ability is comparable to lead silicate glass.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
