- Abstract
- The present scientific article encompasses an analysis of the physicochemical and optical characteristics, as well as adhesion properties of two luminescent materials based on yttrium aluminum garnet, doped with cerium. The aim of the study was to determine the potential usage of these luminescent materials in laser lighting devices. To achieve this, the luminescence spectrum and color diagrams were analyzed when the luminescent materials were subjected to laser radiation with various power and current values. The results revealed that both examined luminescent materials possess high luminous efficiency when current is applied. However, after six months of operation, the luminescent systems exhibited differences in their adhesion properties. Additionally, the study produced a block diagram of a device designed to analyze the physicochemical parameters of laser luminescent systems under the influence of laser radiation with λ = 405–450 nm. With the aid of this device, data on the characteristics of the luminescent materials under different current values were obtained, providing a more precise control over their degradation processes. The investigation demonstrated that both examined luminescent materials can be utilized in laser lighting devices, but one of the luminescent material samples proved to be a more stable and durable material due to its better adhesion with the substrate. The proposed results can be beneficial in the development of new laser lighting tools.
