Transparent glass with photochromism and luminescence has emerged as an attractive material due to its exciting prospects in the fields of information encryption and 3D optical storage. However, thermal stimulation has usually been used to bleach photochromic glass, limiting its applications. Herein, a new entirely photostimulation-induced reversible photochromic glass, doped with lanthanide ions and silver chloride (RE-Ag glass), was explored. Under the alternating stimulation of 365 nm light and a 690 nm laser, reversible photochromism (ΔR t = 91%) from transparent to black and luminescence modification (ΔR m = 93%) with high fatigue resistance were achieved in the RE-Ag glass. This is attributed to the formation and decomposition of silver nanoparticles in the glass host. The optical information can be recorded and erased in the RE-Ag glass with good rewritability and re-erasability, realizing a double-model 3D optical storage. The result highlights a new strategy to explore an entirely photostimulation induced photochromic glass with luminescence for 3D optical storage applications.

Aggredation‐induced electrochemiluminescence (AIECL) promises an efficient strategy for synthesize highly luminescent emitter and co‐reactant for ECL analysis, however, rational control of electrogenerated emission intensity is still challenging. The low electroconductivity and amorphous molecular configuration are intrinsic bottleneck. This work reveals the impact of polyvinyl pyrrolidone backbone regulated silver nanocrystallines (AgNCs/PVP) on the cathode AIECL properties in near infrared region, by employing the Box‐Behnken designed response surface computation model to modulate crystal aggregates. Electron paramagnetic resonance spectroscopy discovered hydrogen radical (HO•) dominant reductive‐oxidative (R‐O) ECL mechanism with AgNCs acting as the co‐reaction accelerator in graphene oxide/persulfate system (GO/S2O82−). Both theoretical calculation and experimental measurement testified that the ECL of AgNCs in GO/S2O82− dependent on the concentration of in situ electrochemical oxidized Ag+. The high efficiency of crystallization‐induced enhanced ECL (CIECL) originates from 1) the effective electron transfer of Ag+ accelerated HO• produce to notable promote radioactive transition, and 2) twisted intramolecular charge transfer from the electron‐rich donor of PVP to electron‐deficient receptor of Ag0 to restrict nonradioactive transition. The AgNCs/PVP with CIECL effect are applied to construct an ultrasensitive platform for miR‐221 assay with a lower detection limit of 7.47 × 103 copies mL−1 than typical qPCR method.

The bright luminescence of silver clusters in glass have potential applications in solid-state lighting, optical memory, and spectral converters. In this work, luminescent silver clusters were formed in the bulk of photo-thermo-refractive glass (15Na2O-5ZnO-2.9Al2O3-70.3SiO2-6.5F, mol.%) doped with different Ag2O concentrations from 0.01 to 0.05 mol.%. The spontaneous formation of plasmonic nanoparticles during glass synthesis was observed at 0.05 mol.% of Ag2O in the glass composition, limiting the silver concentration range for cluster formation. The luminescence of silver clusters was characterized by steady-state and time-resolved spectroscopy techniques. The rate constants of fluorescence, phosphorescence, intersystem crossing, and nonradiative deactivation were estimated on the basis of an experimental study. A comparison of the results obtained for the photophysical properties of luminescent silver clusters formed in the ion-exchanged layers of photo-thermo-refractive glass is provided.
