Penetration-type color tube with phosphors separated by conductive barrier layer
TLDR
A plural-color cathodoluminescent screen for use in a cathoderay tube is described in this paper, where at least two layers of light-emitting phosphors have therebetween a separation layer of electrically conductive oxide material that is substantially translucent to electromagnetic radiation and substantially opaque to the penetration of electron beams of a predetermined velocity.Abstract:
A plural-color cathodoluminescent screen for use in a cathoderay tube wherein at least two layers of light-emitting phosphors have therebetween a separation layer of electrically conductive oxide material that is substantially translucent to electromagnetic radiation and substantially opaque to the penetration of electron beams of predetermined velocity. The screen includes a nucleation to achieve the uniform disposition of an oxidizable metal which when subsequently heated forms the metallic oxide of the separation layer.read more

Nitride type compound semiconductor light emitting element
TL;DR: In a nitride type compound semiconductor light emitting element, a phosphor layer is formed in a multilayer constituting the light emitting elements, and a highly-reflective layer is created at a side plane of the LEM element as mentioned in this paper.
Patent
Luminescent device having phosphor particles about .5 micrometers or less and plasma discharge chamber for generating U.V. light
TL;DR: A luminescent composition is a uniform admixture of a least one phosphor having a particle size of about "one-half" micrometers or less and at least one sol gel compound in an amount sufficient to substantially encapsulate the phosphor.

Display system with rapid color switching
TL;DR: An improved color display system employing a beam penetration type cathode-ray tube with rapid color switching was proposed in this article, where the screen electrode is separated from the accelerating electrodes without the use of an isolating mesh so that the voltage applied to the screen electrodes is switched across only a relatively small capacitance.
