Color tunable (Ba,Ca)ScO2F: Eu2+, Bi3+, K+ perovskite with dependence of excitation wavelength for advanced anti-counterfeiting application

Multisite Fine‐Tuning in Hybrid Cadmium Halides Enables Wide Range Emissions for Anti‐Counterfeiting

“…Consequently, these patterns with various emission colors hold potential applications in multicolor imaging. However, similar to the most previously reported work, the anti‐counterfeiting labels fabricated by one group of tunable emission colors are easily identified (Figure S30) [11,25a,c,26] . To enhance the security of anti‐counterfeiting labels, several groups of tunable emission colors integrating in a pattern were obtained.…”

Luminescence–structure relationships in solids doped with Bi3+

“…The perspectives, in this concern, are real, as demonstrated by the increasing desire for Bi 3+ -doped compounds applicable in e.g. lighting, 230-234 persistent luminescence, [235][236][237][238] anti-counterfeiting [239][240][241][242] or optical thermometry.

Amphiphilic Polyurethane with Cluster-Induced Emission for Multichannel Bioimaging in Living Cell Systems

“…To date, a variety of EDE luminescent materials have been developed, such as single-molecule organic compounds, − multicomponent composites, − quantum dots, , polymeric hydrogels, and metal complexes. − However, these materials usually require harsh synthetic conditions (such as high concentration, high temperature, and high pressure), cumbersome operation conditions, high preparation cost, and poor stability. Moreover, the emission can be too weak at low concentrations and be restricted to a narrow adjustable range of wavelengths. − Therefore, it is still a challenge to construct a single-component EDE material with a simple preparation, low cost, good biocompatibility, and excellent photophysical properties in low concentration applications.…”

“…Moreover, the emission can be too weak at low concentrations and be restricted to a narrow adjustable range of wavelengths. 32 − 34 Therefore, it is still a challenge to construct a single-component EDE material with a simple preparation, low cost, good biocompatibility, and excellent photophysical properties in low concentration applications.…”

“… 14 In addition, under the influence of hydrogen bonds, most of the oxygen atoms in PUP are less than 2.8 Å apart. It is suggested that oxygen atoms within and between molecular chains aggregate to form oxygen clusters 32 ( Table S2 ).…”
