We report photoluminescence properties of Eu-doped layered oxychlorides AE₃Sc₂O₅Cl₂. The Eu ions activated to layered oxychlorides AE₃Sc₂O₅Cl₂ (AE = Sr, Ba). Although they show similar emission spectrum, the excitation spectrum of Ba sample were shifted to low energy. We will discuss about these photoluminescence properties.
