luminescence efficiency and the time resolved spectra of Mn
2+
in nanometer-size ZnS clusters sticked to a chitosan medium were investigated. The causes of the changes of the luminescence properties have been discussed. Experiment shows that the decay time of Mn
2+
in nanocrystals is shorter 2 orders than that of bulk ZnS:Mn. The oscillator strength of Mn ion radiative transition was disscussed according to these results of measurements.
