Photoluminescence properties of single-component white-emitting Ca9Bi(PO4)7:Ce3+,Tb3+,Mn2+phosphors for UV LEDs

A series of Ca₉Bi(PO₄)₇:Ce³⁺,Tb³⁺,Mn²⁺phosphors synthesizedviathe high-temperature solid-state reaction method can emit intense tunable color from purple-blue to red including white under UV excitation, which shows their potential application in UV-pumped white-light-emitting diodes.
