Two-Color Three-State Luminescent Lanthanide Core-Shell Crystals

Abstract

Luminescent core-shell crystals based on lanthanide tris-dipicolinate complexes were obtained from the successive growing of two different lanthanide complex layers. Selective or simultaneous emission of each part of the crystal can be achieved by a careful choice of the excitation wavelength.

Keywords: composite crystals; core-shell crystals; lanthanides; luminescence.
