摘要: The development of materials showing efficient red-emitting persistent luminescence is still an ongoing challenge. As it shows red emission, around 613 nm, Pr3+ remains a good candidate for such application. Indeed, the transition from its 1D2 excited state to 3H4 ground responsible emission. In this paper effect Na substitution in NaNbO3:Pr3+ by K or Li cations term Metal-to-Metal Charge Transfer (MMCT) band position and possible on properties were investigated. MMCT energy increasing tendency with average distance between A site (A = Li, Na, K, Pr) perovskite. most intense (efficient) photoluminescence was observed under excitation Li0.03Na0.97NbO3:Pr3+. relaxation pathways discussed based configurational coordinate model.
