Abstract: A process for incorporating a long persistent phosphor into a fabric material which occurs by firing a phosphor within a crucible, then grinding the resulting aggregate into a phosphor particulate of specified size, encapsulating the phosphor particulate within a water impervious coating material and then applying a specified ratio by weight of the encapsulated phosphor particulates into the fabric material. Further, a fibrous product is described incorporating encapsulated long persistent phosphor particles.

Abstract: A process for incorporating a long persistent phosphor within a settable material includes firing a doped phosphor to obtain a phosphor having a persistence that ranges from minutes to hours. The fired phosphor is then ground into a phosphor particulate having a mean domain size. Typical particulate mean domain size ranges from 1 to 60 microns. The phosphor particulate is thereafter encapsulated within a water impervious coating material such as silicon oxide or fluoride. The coated phosphor particulate is then mixed in a specified volume ratio within the settable material while the settable material is in a pre-set state. Typical formulation ratios range from 0.1 to 30 volume percent of particulate. A method of forming a phosphorescent solid article is also disclosed.

Abstract: A process for incorporating a long persistent phosphor within a non-settable material includes firing a doped phosphor to obtain a phosphor having a persistence that ranges from minutes to hours. The fired phosphor is then ground into a phosphor particulate having a mean domain size. Typical particulate mean domain size ranges from 1 to 60 microns. The phosphor particulate is thereafter encapsulated within a water impervious coating material such as silicon oxide or fluoride. The coated phosphor particulate is then mixed in a specified volume ratio within the non-settable material. Typical formulation ratios range from 0.1 to 30 volume percent of particulate.

Abstract: A transparent tubular member containing a phosphorescent material providing a degree of persistent illumination. The tubular member includes a first end and a second end, an outer diameter and an inner diameter establishing between the outer diameter a selected thickness. A volume of the phosphorescent material is encapsulated within the elongate tubular member and is responsive to an irradiating light source to charge the phosphorescent material to a desired degree of luminescence and so that the tubular member emits the luminescence of the phosphorescent material over a period of time.
