## Abstract We have studied the optical properties of ZnTe nanocrystals (ZnTeβnc) embedded in a SiO~2~ matrix by spectroscopic ellipsometry. The ZnTeβnc are embedded in a SiO~2~ matrix by ion implantation technique. The dose of 2.9βΓβ10^16^βcm^β2^ of tellurium and zinc ions are implanted in a 250βn
Si nanocrystals (Si-ncs) embedded in SiO 2 /SiN x multilayer structures can be of interest for optoelectronic devices such as solar cells. However, controlling the size and density of the Si-ncs is strongly requested for an efficient use in a functioning solar cell device. In this work, SiO 2 and S
