Integration of luminescent rare earth ions and iridescence into a zirconium oxide photonic material is attractive for the design of new optical devices. The free-standing chiral nematic mesoporous films of ZrO2:Eu(3+) are assembled by a hard-templating approach using nanocrystalline cellulose-templated silica. The ZrO2:Eu(3+) films show tunable optical properties. The chiral nematic structured ...

The photophysical properties of films of organic-inorganic lead halide perovskites under different ambient conditions are herein reported. We demonstrate that their luminescent properties are determined by the interplay between photoinduced activation and darkening processes, which strongly depend on the atmosphere surrounding the samples. We have isolated oxygen and moisture as the key element...

An understanding of the aggregates and properties of positional isomers can not only uncover how a slight difference in molecular structure alter crystal packing and bulk solid-state properties, but also plays an important role in developing new types of molecule-based functional materials. Herein, we report a study of the molecular packing and static/dynamic luminescence properties of three cy...

We report photoluminescence (PL) study of BexCd1KxSe epitaxial layers (x!0.21) grown by molecular beam epitaxy on InP substrates. Continuous wave PL spectra are taken within a 4.2–300 K temperature range. We observe an anomalous ‘s-shaped’ temperature dependence of emission energy and a severe decrease of emission intensity with the increase of temperature. We explain an ‘s-shaped’ temperature ...

A new class of luminescent cyclometalated iridium(III) polypyridine fluorous complexes has been designed; the fluorous pendant not only plays an important role in the photophysical and biological properties of the complexes, but also allows the facile isolation of biomolecules labeled with these complexes with fluorous solid-phase extraction (FSPE).
