Abstract

The processes of energy transfer and diffusion of photons emitted by Nd3+ ions embedded into a glass sample were investigated. The luminescence resolved in space allowed the observation of the photons’ spatial distribution. In this paper, we propose a fuzzy mathematical model that permits carrying out calculations based on the neighborhood luminescence intensity of the excitation spot laser. This proposed model differs from other well-known ones in the literature because it shows clearly the luminescence intensity profile on the sample surface.
