Optical properties of Eu, Dy, Mn activated M2SiO4, (M2=Ca, Sr, Zn) orthosilicate phosphors

► Alkaline orthosilicate phosphors are modified solid state synthesis method. ► Excitation wavelength of prepared phosphors is in the near UV range. ► Emission of all prepared phosphors is in the visible range of the spectrum. ► Prepared materials optical characterized are well interested. ► Prepared phosphors may be useful for applications like solid state lighting.
