Strongly confined NaVO⁺ segregation and its thermoresponsive functionality at the interface between simple sputter-deposited amorphous vanadium oxide thin films and soda-lime glass is substantiated in this work by in situ temperature-controlled time-of-flight secondary-ion mass spectrometry (ToF-SIMS). The obtained ToF-SIMS depth profiles provide unambiguous evidence for a reversible transformation that causes systematic switching of the NaVO⁺/Na⁺ and Na⁺/VO⁺ intensities upon cycling the temperature between 25 and 340 °C. Subsequently, NaVO complexes are found to be reversibly formed (at 300 °C) in vanadium oxide-diffused glass, leading to thermoresponsive electrical behavior of the thin-film glass system. This new segregation and diffusion-dependent multifunctionality of NaVO⁺ point toward applications as an advanced material for thermoelectrical/optical switches, in smart windows or in thermal sensors.

VO+-扩散钠钙玻璃的界面驱动热电开关性能

在这项工作中，通过原位温度控制飞行时间二次离子质谱法 (ToF) 证实了在简单溅射沉积的非晶氧化钒薄膜和钠钙玻璃之间界面处的强限制 NaVO ⁺偏析及其热响应功能-模拟人生）。获得的 ToF-SIMS 深度剖面为导致 NaVO ⁺ /Na ⁺和 Na ⁺ /VO ⁺系统切换的可逆转换提供了明确的证据在 25 到 340 °C 之间循环温度时的强度。随后，发现 NaVO 复合物在氧化钒扩散玻璃中可逆地形成（在 300°C 下），导致薄膜玻璃系统的热响应电行为。NaVO ^{+ 的}这种新的分离和扩散依赖的多功能性指向作为热电/光开关、智能窗户或热传感器的先进材料的应用。
