The known and obtained in this work dependences of the 4,2, 77 and 295 K peak positions hvm of the Cd1-xZnxTe edge emission bands induced by: (a) annihilation of free X and bound on shallow neutral acceptors A<^>0 or shallow neutral donors D<^>0 excitons A<^>0X and D<^>0X and (b) recombination of free and shallow donor bound electrons with free holes on Cd1-xZnxTe composition x (<$Ex~symbol Г~0,28>) are analyzed in detail. It is shown that the 4,2 K peak position of the A<^>0X induced emission band used for the exact x determination could be related with some problems arising from variety of the 4,2 K <$Eh nu sub m (A sup 0 X)> vs. x dependences. As a result of the pointed problem, analysis of the 4,2 K <$Eh nu sub m (A sup 0 X)> vs. x dependences permits to find the x value with some inaccuracy (some unknown factors shift the energy position of the A<^>0X bound exciton are responsible for this fact). The noticeable (differing from the expected theoretical ones) differences of the peak positions of emission bands <$Eh nu sub m> induced by radiative annihilation of D<^>0X bound excitons at 295 K, radiative recombination of donor bound electrons D<^>0 with free holes h at 300 K and radiative annihilation of free electrons e and holes at 300 K, i.e. of 295 K <$Eh nu sub m (D sup 0 X)>, 300 K <$Eh nu sub m (D sup 0 h)> and 300 K <$Eh nu sub m (eh)> values, accordingly, vs. x dependences are observed and briefly analyzed.
