Perylene diimide derivative dispersed in LDH as a new efficient red-emitting phosphor for LED applications

Abstract

Perylene diimide-based dyes substituted by four sulfonate groups at their bay position are known to be extremely sensitive to their mutual  –  intermolecular interaction. They do not emit...

“…Figure a–c displays the absolute photoluminescence quantum yields (PLQY abs ) as a function of the relative interleaved phosphor content for the three series. The PLQY abs of DS–TSP x –LDH as a function of the TSP amount is shown in Figure S2a as the results relating to this fluorophore and its intercalation in an LDH matrix have been the subject of a dedicated study, recently published . The dotted lines in Figure and Figure S2 correspond to excitation wavelengths of common UV and blue commercial LED chips at 385, 450, and 465 nm.…”

“…The PLQY abs of DS−TSP x −LDH as a function of the TSP amount is shown in Figure S2a as the results relating to this fluorophore and its intercalation in an LDH matrix have been the subject of a dedicated study, recently published. 49 The dotted lines in Figure 4 and Figure S2 correspond to excitation wavelengths of common UV and blue commercial LED chips at 385, 450, and 465 nm. Figure 4d−f and Figure S2c illustrate the variation in internal photoluminescence quantum yield (PLQY int ), absorbance (Abs), and absolute photoluminescence quantum yield (PLQY abs ) as a function of the PD content within LDH under excitation at 465 nm.…”
