METHODS OF PHOSPHOR SYNTHESIS: COMPARATIVE RESEARCH
Abstract
The article presents the results of a comparative study of the methods for synthesizing luminophores used in signal materials to facilitate the search for victims. The method is selected based on the requirements for the characteristics of the finished signal product. The work considers such synthesis methods as sol-gel/Pechini method, solid-phase reaction, solvothermal reaction, coprecipitation, sonochemical synthesis, microwave methods and combustion synthesis methods. Particular attention is paid to the solid-state synthesis method, which is suitable for mass production of luminophores from a mixture of solid source materials. The luminophores obtained by this method are highly stable, dispersed and relatively inexpensive. To obtain luminophores with specified properties, it is recommended to use sol-gel synthesis technology.
