Ultraviolet to near-infrared conversion in Nd3+ doped strontium cerate nanophosphors

Ruddlesden-Popper phase A2BO4 oxides: Recent studies on structure, electrical, dielectric, and optical properties

“…doped Sr CeO phosphors have attracted lots of attention from the r e s e a r c h e r s [ 1 4 8 ] . Sr CeO : Eu (Dy , Tm ) phosphors have exhibited strong red (yellow, blue) emission which makes them potential for display applications such as UV-LEDs [159]. Rare earth ions (Ho , Er , Tm , a n d Yb ) d o p e d Sr CeO phosphors have been studied for their application as lasing materials or spectral conversion materials [159].…”

Dy doped phosphors have shown two intense emission at 484 nm (blue) and 575 nm (yellow) useful for white light emission based optical devices.…”

UV-to-NIR Wavelength Conversion of π-Conjugated Polymers Based on Pyrene-Substituted Boron-Fused Azobenzene Complexes

“…14 So far, however, there are few examples with UV-to-NIR wavelength conversion 14,15 except for the WCMs based on the precious and resource-constrained lanthanoid luminophores. 6,16,17 A major barrier is the lack of suitable energy acceptor, showing solid-state NIR emissive properties. In terms of their complicated and highly planar structures, most conventional NIR dyes have poor designability to assemble FRET systems and lose their luminescence in the solid state due to intermolecular interaction known as aggregation-caused quenching (ACQ), respectively.…”

“…In ideal FRET pairs, only fluorescence (FL) derived from the energy acceptor should be observed upon excitation of the energy donor, which resulted in the large pseudo-Stokes shift, which is apparent large difference between the excitation wavelength and the peak position of emission bands based on the energy transfer .
