III addition to the well known intrinsic luminescence at 4.22 eV, two newuuminescences at 3.67 and 2.78 eV are found under the excitation in tlte funda-mental absorrtion bands at low temr>eratures in undored Nal cr>zstals. Tlte2.78 eV luminescence appears under the excitations in the band-to-band transitionregion and the first exciton absorr>tion band, but the 3.67 eV luminescence art>earsonly under the excitation in the exciton band. Three distinctive exponential decaytime contr>onents are observed for tl?ese new luminescences whose decay timesvary with temr>erature. The intrinsic character of these two luminescences arediscussed. In Tl"-dor>ed Nal, it is concluded that the energy transfer from freeexcitons to Tl" ions takes place at low temnperatures
