Abstract: A new method for production of ZnS:M[M=Mn, Cu, Cu(Al)] nano-phosphor powders was described. The size of ZnS:M
nanoparcicles can be well controlled from 1.8nm to 3nm by adjusting the molar ratio of mercaptoacetic acid to monomer of methacrylic acid. Selected area
electron diffraction (SAED) and X-ray diffraction (XRD) demonstrate that the ZnS:M nano-phosphor powders have zinc blende crystal structure. TEM image
indicates that the ZnS:M nano-phosphor powders have uniform size distribution. The photoluminescence (PL) of ZnS:Mn reveals that the ZnS:Mn nano-phosphor
powder has greatly luminescent efficiency, compared with bulk ZnS:Mn.

Key words: nano-phosphor powders, ZnS:M
