Emissions from charge transfer states of rare gas halide RgX molecules (XeF, KrF), alkali halide ions AX (CsF, CsCl, RbF), from vibrational states of CO and NO, and also from CO₂ molecules doped into rare gas and N₂ solids combine the known properties of gas phase lasers transitions with high densities of excited states attainable in the condensed phase. Cryogenic solids prepared by direct condensation of gas mixtures are grown routinely and allow for solid state laser experiments and also observation of strong luminescence bands in the VUV (B-X excimer transition of RbF at 136 nm), UV (B-X transition of CsF and CsCl at 196 and 210 nm; CsF(C-A) at 211 nm; XeF(D-X) at 269; 286 and 301 nm in Ne, Ar and Kr hosts, respectively), visible (XeF(B-X) and (C-A) at 411;541 nm) and infrared wavelength region (4.96; 5.4 and 16 micrometers bands of CO, NO and CO₂).
