Strong coupling between a cavity and transition dipole moments in emitters leads to vacuum Rabi splitting. Researchers have not reported strong single emitter dielectric at room temperature until now. In this study, we investigated the photoluminescence (PL) spectra of colloidal quantum dots on surface SiO2/Si material various collection angles temperature. We measured corresponding reflection for compared them with PL spectra. observed spectral splitting regarded it as material. Upper polaritons lower exhibited anticrossing behavior. from single-photon emission Through analysis, attributed bound states continuum low-refractive-index/high-refractive-index hybrid
