Abstract	Abstract We present the structural and optical results of (100− x )SiO 2 : x ZnO compounds with x =0, 20, 40, 60, 80, and 100, containing 1 mol% of Er 3+ prepared by a simple chemical route. It was evaluated the crystallization effect on the erbium ions emission around 1533 nm due to 4 I 13/2 → 4 I 15/2 transition. Structural analyses using X-Ray Diffraction (XRD) and Fourier Transform Infrared Spectroscopy (FTIR) techniques showed that the prepared material present crystalline phases, the ZnO hexagonal (Zincite) and Zn 2 SiO 4 rhombohedral. The relative content of crystalline phases as well the optical emissions in the infrared region are dependent on the composition and heat treatments. High-resolution transmission electron microscopy revealed average 5 nm sized Zn 2 SiO 4 nanocrystals homogeneously dispersed into amorphous silica-based matrix. The Er 3+ doped Zn 2 SiO 4 crystalline phase are the most promising material to be used in optical system.
