Zn2SiO4:Mn2+ Nano-Particles Grown in Porous Silicon

Abstract

We have succeeded to grow nano-crystalline Zn(2)SiO(4) : Mn(2+) particles by chemical impregnation of porous silicon layers and heat treatment. Two different classes of samples have been obtained: green luminescence samples at 525 nm and yellow luminescent ones at 575 nm. We identify the green luminescence as the conventional luminescence of the alpha phase of Zn(2) SiO(4) : Mn(2+) however the yellow luminescence comes from the beta phase of Zn(2)SiO(4) : Mn(2+). XRD peaks of the yellow luminescent samples show wide and weak peaks indicating smaller particles compared to green luminescent particles. We discuss about the conditions which result in either green or yellow luminescent samples.
