Abstract

Trivalent dysprosium (Dy³⁺)-activated inorganic phosphors have become fascinating due to tunable yellow/white light emission. Nevertheless, the challenge for solid-state lighting utilization is achieving highly luminous efficiency and thermostability of Dy³⁺. In this study, a new Ba₅P₆O₂₀ (BPO) phosphor is developed via replacing Ba²⁺ with Dy³⁺. The luminescence behaviors in response to the occupancy sites and content of Dy³⁺ activators are thoroughly investigated. Subsequently, to enhance comprehensive luminescence performances, alkali metal ions are co-doped based on charge compensation strategy. Especially, the K⁺ compensation can induce that the luminous efficiency and intensity are increased by around 4 and 2 times, separately. Meanwhile, the high thermal quenching resistance and chromaticity shifting resistance for Dy³⁺ emissions are achieved. Finally, the optimized BPO:5%Dy³⁺,5%K⁺ sample is employed to obtain a satisfactory solid-state white lighting source.

期刊介绍： Progress in Solid State Chemistry offers critical reviews and specialized articles written by leading experts in the field, providing a comprehensive view of solid-state chemistry. It addresses the challenge of dispersed literature by offering up-to-date assessments of research progress and recent developments. Emphasis is placed on the relationship between physical properties and structural chemistry, particularly imperfections like vacancies and dislocations. The reviews published in Progress in Solid State Chemistry emphasize critical evaluation of the field, along with indications of current problems and future directions. Papers are not intended to be bibliographic in nature but rather to inform a broad range of readers in an inherently multidisciplinary field by providing expert treatises oriented both towards specialists in different areas of the solid state and towards nonspecialists. The authorship is international, and the subject matter will be of interest to chemists, materials scientists, physicists, metallurgists, crystallographers, ceramists, and engineers interested in the solid state.
