Materials for tritium solid-state radioluminescent light sources (SRLS). Modified technique of phosphor screens manufacturing

Abstract

Radioluminescent light sources (RLS) are very promising energy-saving types of devices which are highly sought in various fields of industry due to their energy independence, self-reliance and longevity. The key idea of SRLS is bonding the working isotope (tritium) in the solid matrix and combining it with the phosphor. This approach allows to decrease the radiological hazard and create safe and endurable light sources of various forms and sizes. The main factor of raising the SRLS effectivity is providing the closest contact between the tritiated carrier matrix and phosphor screen. Also, achieving the optimal thickness for the phosphor screen is a crucial task for the SRLS creating. The screen being too thin will not be able to provide enough brightness, and the one too dense will absorb all the light. So the development of the working method of making the strong and uniform phosphor screens of adjustable thickness is indeed a very promising challenge.
