Abstract

The energy donor’s superlative antenna effect efficiently improves the performance of the reaction centers of light-harvesting systems. Consequently, we successfully leveraged this exceptional capability to develop high-performance X-ray imaging scintillator screens. Electron microscopy imaging with atomic-level resolution and theoretical calculations have revealed that within lanthanide-ion-doped CaMoO₄ (Ln³⁺-CaMoO₄, Ln = Eu or Tb) quantum dots (QDs), Ln³⁺ is uniformly distributed throughout the CaMoO₄ lattice. The synergy between Ln³⁺ and CaMoO₄ QDs amplifies the X-ray photon absorption capacities and enables efficient energy transfer from the CaMoO₄ QD antenna to the Ln³⁺ emission center, significantly enhancing the X-ray sensitivity and imaging resolution of QD screens. To illustrate, the CaMoO₄:(Eu³⁺)_0.20 QD screens exhibit an impressive X-ray imaging resolution, exceeding 23 lp/mm, outperforming most recognized organic and conventional inorganic scintillators. These findings can position doped QDs as promising scintillators for X-ray imaging with potential application in medical radiology and security screening.
