Two new types of radioluminescent (RL) compositions light sources are provided. The first type is an all-organic system, consisting of covalently bound tritium within a solid, optically clear polymeric matrix. The matrix contains organic scintillation dyes that capture excitation energy from beta decay and red-shift the energy in a stepwise fashion, after which a chosen wavelength is emitted as fluorescence. The second type of RL light source consists of a zeolite crystalline material, in which material's intralattice spaces a tritiated compound and a luminophore are sorbed, and which material is optionally further dispersed in a refractive index-matched polymer matrix. 10 refs.
