Abstract
As a large type of inorganic layered compounds with diversity of composition in host layer and interlayer anions, layered double hydroxides (LDHs) have been intensively studied toward construction of advanced photofunctional materials. In this chapter, the optical properties of LDH materials and related potential applications—mainly involving the functionalities of LDH layers (such as tunable color, infrared radiation (IR) absorption, and ultraviolet (UV) shielding)—will be described firstly. Then, we will review the development of intercalated luminescent materials by adjusting both the host layer and guest molecules, in which the static and dynamic photofunctional modulations have been focused. Due to the host–guest and guest–guest interaction, fluorescence properties of composites can be effectively altered, and intelligent materials with stimuli-responsive performance can be further obtained. Finally, perspectives on the future development of LDH-based solid-state luminescent materials are addressed.
