Well-crystallized　gamma-MnS　films　in　a　pure　phase　have　been　deposited　on　commercial　glass　substrates　by　chemical　bath　deposition.　The　structure　and　morphology　of　the　obtained　gamma-MnS　film　were　characterized,　and　the　results　showed　that　the　film　was　composed　of　asymmetric　hexagonal　crystals　with　a　size　of　500-1000　nm.　The　photo　luminescence　of　the　gamma-MnS　film　has　been　studied　from　295　K　down　to　30　K　and　exhibited　two　emission　bands　centered　at　1.8　and　1.66　eV,　respectively.　The　temperature　dependence　of　photoluminescence　was　also　observed　and　interpreted　using　the　spin-wave-assist　photoluminescence　model.　(C)　2003　Elsevier　B.V.　All　rights　reserved.
