Photochromic properties in Eu3+ doped Sr2SnO4
Published online by Cambridge University Press: 10 May 2013
Abstract
We report the photochromism (PC) in Eu3+ doped Sr2SnO4. The Sr2SnO4:Eu3+ is sensitive to UV light (λ < 350 nm) and turns to purple color. When visible light (λ= 400-700 nm) is irradiated, the colored Sr2SnO4:Eu3+ is bleached. From the results of absorption spectrum, Sr vacancies in the host lattice and charge transfer transition between Eu3+-O2- is responsible for PC process of Sr2SnO4:Eu3+.
