Amorphous--Si/sub 1-x/ Sn/sub x/ :H alloys have been prepared by dc and rf sputtering of composite Si--Sn targets in Ar--H/sub 2/ gas mixtures. /sup 119/Sn conversion electron Moessbauer spectroscopy and x-ray diffraction reveal the Sn to be incorporated into the films in at least four distinct sites, the relative populations of which depend strongly on preparation conditions. The Moessbauer resonance from the substitutional Sn in the a-Si:H matrix is well characterized by a quadrupole splitting of 0.46 +- 0.05 mm/s independent of x and preparation conditions. Experimental procedures have been found such that samples can be produced which contain only the substitutional Sn site.
