Activator-doped aluminum oxynitride (γ-AlON) could provide an extremely versatile transparent ceramic with photothermal feedback, opening the door to many new applications and devices for use in extreme conditions. However, existing AlON transparent ceramics have failed to achieve temperature-responsive luminescence. To address this, a simple-to-implement luminescent rare-earth doping strategy for fabricating AlON transparent ceramic with efficient temperature feedback is proposed and demonstrated. Luminescent PrO serves as the illustrative example. Benefiting from the liquid phase formed by PrO and the thermal coupling between the P and P levels of Pr, AlON ceramics doped with PrO exhibit significantly elevated transparency and temperature-responsive luminescence. More importantly, the AlON:Pr ceramic can serve as photothermal feedback windows, which presents attractive performance. This paradigm fills an important gap in the AlON transparent ceramics for temperature feedback windows, and will inspire the controllable design of luminescent rare-earth doped AlON ceramics for use in harsh conditions.

通过发光稀土掺杂在 AlON 陶瓷中同时实现显着的透明度增强和有效的温度反馈

掺杂活化剂的氮氧化铝（γ-AlON）可以提供一种具有光热反馈功能的极其通用的透明陶瓷，为许多在极端条件下使用的新应用和设备打开了大门。然而，现有的AlON透明陶瓷未能实现温度响应发光。为了解决这个问题，提出并论证了一种易于实施的发光稀土掺杂策略，用于制造具有高效温度反馈的 AlON 透明陶瓷。发光的 PrO 作为说明性的例子。受益于 PrO 形成的液相以及 Pr 的 P 和 P 水平之间的热耦合，掺杂 PrO 的 AlON 陶瓷表现出显着提高的透明度和温度响应发光。更重要的是，AlON:Pr陶瓷可以作为光热反馈窗口，表现出诱人的性能。这一范例填补了用于温度反馈窗口的 AlON 透明陶瓷的重要空白，并将激发在恶劣条件下使用的发光稀土掺杂 AlON 陶瓷的可控设计。
