Visible‐Light‐Excited Optical Thermometry in Ca3Sc2Si3O12: Er3+ via an Efficient Eu2+ Bridge
Rare Metals, Volume 45, Issue 7, July 2026.ABSTRACT Er3+ ions are promising for optical thermometry due to their thermally coupled levels. However, their parity‐forbidden transitions result in weak and narrowband absorption, which restricts excitation to infrared lasers (e.g., 808, 980, or 1550 nm). Moreover, the single emission center inherently limits temperature sensitivity. In this work, we
