“Background In modern materials science, considerable attention has been paid to the precise manipulation and development of new user-friendly methods for fabricating a range of inorganic systems in the nanoscale region. Among these inorganic systems, bifunctional magnetic-luminescent composites are particularly attractive because of their unique magnetic and luminescent properties in combination in a single particle. Each bifunctional particle normally has a paramagnetic core structural domain covered by a luminescent shell domain.
