Invisible near‐infrared thermo‐stimulated luminescence from carbon dots enabled by stepwise energy transfer for concealed information encryption

Responsive Materials, EarlyView.
A fully metal‐free near‐infrared (NIR) thermo‐stimulated luminescent system is developed by embedding carbon dots into a carbon nitride matrix and integrating multistage Förster resonance energy transfer. The system exhibits long‐term charge retention, rewritable optical memory, and highly concealed NIR readout, promising for secure data encryption and

Efficient water‐soluble blue/red‐emissive carbon dots matching plant absorption spectra: Synthesis, tunable control, and their applications in promoting plant growth

Responsive Materials, EarlyView.
Guided by the spectral demand of plant photosystems, this review summarizes the synthesis, emission regulation, dual‐emission design, and gram‐scale production of CDs for agricultural applications. Spectrally matched blue‐ and red‐emissive CDs enhance plant light utilization by converting underutilized light into photosynthetically active radiation and

Cellulose‐based films with ultralong full‐color circularly polarized room‐temperature phosphorescence and bidirectional dissymmetry tuning

Responsive Materials, EarlyView.
A universal co‐assembly strategy of CNCs, PVA and phosphorescent chromophores is proposed to fabricate CP‐RTP films with an ultralong lifetime of 1.588 s. FRET‐based dye doping enables full‐color CP‐RTP, and integration with an additional CNC‐based film enhances CPL and achieves tunable luminescence handedness, with the glum factor from −0.7782 to 0 ...

Synthesis of Samarium‐incorporated X‐ray‐sensitive nanoparticles and hydrogels: Diverse applications in radiation monitoring and dynamic information display

Smart Molecules, EarlyView.
Sm3+‐doped α‐NaLuF4 and β‐NaLuF4 were synthesized. The X‐ray‐activated persistent luminescence abilities and afterglow properties can be well controlled. Sm3+‐doped β‐NaLuF4 exhibits remarkable afterglow ability. The hexagonal β‐NaLuF4:3%Sm3+‐incorporated hydrogel can be further programmed with other types of hydrogels to enable tunable emission ...

Synthesis and Crystal Structure and Characterization of Copper(I) Thiocyanato–Thiuram Disulfide, CuSCN[(SCNH2)2S2]

Zeitschrift für anorganische und allgemeine Chemie, EarlyView.
The copper(I) thiocyanate adduct with thiuram disulfide, CuSCN[(SCNH2)2S2], was synthesized via mechanochemical grinding of equimolar amounts of CuSCN and (SCNH2)2S2 with minimal acetone. Structural analysis using PXRD data reveals infinite zigzag chains of distorted tetrahedra around copper along [001], interconnected into two‐dimensional wavy ...
