The inorganic compounds based on crystalline solid solutions are proposed as the materials for visually observable transformation of ionizing radiation. The energy spectra of Ca1‑xLuxF2+x: Eu2+ crystals have showed that the light output is consistently increased upon an increase in the parameter Zeffect related to the advanced LuF3 content. The efficient excitation energy transfer between the impurity rare-earth ions Eu2+ and Pr3+ in the mixed crystals of Ca1‑xLuxF2+x synthesized by the horizontal directional crystallization has been studied. The results of luminescence studies during registration of the γ-, X-ray and short-wave UVC radiation confirm the process of excitation energy transfer from the Eu2+ ions to Pr3+ in Ca1‑xLuxF2+x and allow to consider the Eu2+ ions as an efficient sensitizer of Pr3+ ions. The sensitization-enhanced radiation of Pr3+ ions converts the UV radiation of Eu2+ excited by the γ-quanta into the visible spectral band.
