Photonic Effects for Magnetic Dipole Transitions.

ABSTRACT: The radiative transition probability is a fundamental property for optical transitions. Extensive research, theoretical and experimental, has been conducted to establish the relation between the photonic environment and electric dipole (ED) transition probabilities. Recent work shows that the nanocrystal (NC)-cavity model accurately describes the influence of the refractive index n on ED transition rates for emitters in NCs. For magnetic dipole (MD) transitions, theory predicts a simple n³ dependence. However, experimental evidence is sparse and difficult to obtain. Here we report Eu³⁺-(with distinct ED+MD transitions) and Gd³⁺-(MD transitions) doped β-NaYF₄ NC model systems to probe the influence of n on ED and MD transition probabilities throug
