Abstract

Ba₂ZnS₃:Mn (BZS), SrGa₂S₄:Eu, and BaAl₂S₄:Eu nanoparticles phosphor materials were prepared by a break down method, namely the ball-milling method. Several-nanometer-size stoichiometric and dispersed nanoparticles were achieved. Red color phosphor material, namely BZS, was sprayed on the glass substrate. Mn doped BZS absorbs ultra violet light and emits red light peaking at around 640nm. The transparent nanoparticle layer absorbed short wavelength light and converted to long wavelength light for the Si solar cell application.
