Phosphors are received in the form of micro and nanopowders (NP). It is established that upon transition from micro- to NP, there is a modification of an vibration range of nanosamples: density of oscillatory conditions is impoverished. Width of the forbidden zone of silicates increases upon transition from micro to a nanocondition. In a range of a luminescence of nanophosphors there is a broadening of lines of a luminescence and change of their intensity.
