Implication

Theoretical study uncovers radiationless energy transfer via forbidden transitions in inorganic phosphors, highlighting distinct ranges for dipole, quadrupole, and exchange interactions.

Key Points

  • Extend the resonance energy transfer theory beyond allowed transitions to explain sensitized luminescence across forbidden transitions in inorganic crystalline phosphors.
  • Expanded resonance energy transfer formulation to incorporate higher-order multipole transitions and electron exchange interactions.
  • Evaluated the analytical dependence of energy transfer efficiency on sensitizer-activator distance, spatial lattice sites, activator concentrations, and temperature.
  • Identified that radiationless energy transfer operates primarily through three mechanisms in order of decreasing strength: electric dipole-dipole, electric dipole-quadrupole, and quantum exchange interactions.
  • Demonstrated that sensitizers govern approximately 10^3 to 10^4 surrounding lattice sites via dipole-dipole transfer, around 10^2 sites via dipole-quadrupole transfer, and roughly 30 sites via exchange effects.
