摘要：

The photoluminescence properties of alpha-Zn2SiO4 nanoparticles formed in the SiO2 by means of ion implantation and subsequent 900 degrees C, 1 hour annealing in air atmosphere. Both X-ray diffraction, optical and photoluminescence (PL) spectra confirm the formation of willemite phase Zn2SiO4 in SiO2 matrices. The characteristic 2.4 eV PL band observed resembles the properties of classi-cal Zn2SiO4: Mn phosphor, though no manganese were introduced into the samples. PL excitation spectra demonstrate the contribution of willemite and silica band states, thus suggesting interphase energy transfer mechanism. Thermal quenching and lifetimes of the luminescence observed provide the clues to figure out the nature of emission centres. (C) 2015 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim
