The ability to produce and distinguish microparticles containing >1100 spectral codes via the ratiometric incorporation of lanthanide nanophosphors is demonstrated. It is shown that 98% of these microparticles, which are termed MRBLEs (microspheres with ratiometric barcode lanthanide encoding), can be assigned to a code with >99.99% confidence, representing the largest purely spectral code set produced to date.

The optical characteristics of devitrite and liquid crystal are integrated to fabricate an electrically variable optical diffuser. The magnitude and the transmission scattering angle of the device are tuned by changing the voltage between graphene and indium tin oxide electrodes to achieve optical diffusion up to ±60°.
- A Complete Quantitative Analysis of Spatio-Temporal Dynamics of Excitons in Functional Organic Light-Emitting Diodes

The spatio-temporal dynamics of excitons in functional polymer light-emitting diodes reveal that singlet–triplet annihilation (STA) is significantly higher than the often invoked singlet–polaron annihilation (SPA). STA holds back the efficiencies of PLEDs and further realization of organic injection lasers. Additional singlets are found in F8BT that are related to thermally activated delayed fluorescence (TADF), as triplet–triplet annihilation (TTA) alone cannot account for the observed high external quantum efficiencies.
- Unlocking the Potential of Pyrimidine Conjugate Emitters to Realize High-Performance Organic Light-Emitting Devices

A series of pyrimidine-conjugated thermally activated delayed fluorescent (TADF) emitters is developed. Using a highly emissive green pyrimidine conjugate emitter and sophisticated device engineering, the optimized device operates on 2.2 V at 1 cd m−2 and exhibits a superior performance with an ηext of over 25%, an ηp of over 110 lm W−1, and exceptionally low efficiency roll-off.

An ultrasensitive visible-light transistor was fabricated by applying one-step solution-processed 2D perovskite (C6H5C2H4NH3)2SnI4 film with high crystallinity as the channel layer. The phototransistor shows high photoresponsivity over 104 A W–1 to very week visible-light signals because of the inorganic charge-carrying sheets extending in the direction of carrier transport in the field-effect transistor.
