Contribution

It introduces a new theoretical framework using density matrix formalism to analyze quantum systems coupled with nanoobjects, challenging existing approaches.

Findings

Questionable validity of common approaches in literature

Proposes an alternative density matrix-based model

Provides insights into luminescence enhancement mechanisms

Abstract

The problems of the luminescent enhancement and life time shortening for the inverted quantum system (QS) are analysed. The commonly accepted in publications approach appears to be questionable from the point of view of basic principles. An alternative approach using the well-known density matrix formalism and kinetic equation for the electrons in the coupled nano object is suggested.
