上转换控制：在外延生长的镧系元素掺杂BaTiO 3薄膜上施加较低的偏压，可显著增强上转换发光。此外，光致发光（PL）强度可以用交流电场调制（见图）。这种方法提供了一种实时和动态的方式来控制光致发光。
Upconversion control: Applying a relatively low bias voltage to an epitaxial lanthanide-doped BaTiO3thin film results in a significant enhancement of the upconversion emission. Moreover, the photoluminescence (PL) intensity can be modulated with an ac electric field (see picture). This approach provides a real-time and dynamic way to control photoluminescence.
