Photoluminescence Properties of Er/Pr‐Doped K 0.5 Na 0.5 NbO 3 Ferroelectric Ceramics

Er/Pr‐doped K 0.5 Na 0.5 NbO 3 ceramics have been fabricated and the effects of Pr 3+ on their photoluminescence properties have been investigated systematically. The visible upconversion emissions, near‐infrared and mid‐infrared downconversion emissions of Er 3+ ions under the excitation of 980 nm...
