Growth of Millimeter‐Sized BaTaO2N Single Crystals by an NH3‐Assisted BaCl2 Flux Method

Advanced Functional Materials, EarlyView.
Millimeter‐sized BaTaO2N single crystals are successfully grown from a BaCl2 flux under NH3 flow. Their comprehensive characterization, including dielectric properties, is demonstrated, and the possible growth mechanisms are discussed. Abstract Perovskite‐type oxynitrides have attracted considerable attention due to their excellent photocatalytic ...

RoHS‐Compliant, Cu‐Zn‐In‐Se‐Based Core/Multi‐shell Quantum Dots with Efficient and Tunable Short‐Wave Infrared Emission

Advanced Functional Materials, EarlyView.
An innovative combination of size‐controlled template synthesis, partial cation exchange reactions, and dual shell passivation offers a new class of RoHS‐compliant, heavy metal‐free Cu‐Zn‐In‐Se/ZnS/Al2O3 core/shell/shell quantum dots (QDs), exhibiting long‐range tunability, highly efficient SWIR emission with remarkably narrow photoluminescence ...

Upconversion Nanoparticles Embedded Photonic Contact Lens for Transepithelial Corneal Crosslinking Using Hyaluronate – Riboflavin Conjugate

Advanced Functional Materials, EarlyView.
A minimally invasive, transepithelial corneal cross‐linking (TE‐CXL) approach is presented using upconversion nanoparticles (UCNPs)‐loaded contact lenses (UCLs), after topical delivery of hyaluronate–riboflavin conjugates. The NIR‐to‐UV/blue light conversion by UCNPs in a UCL can activate riboflavin for TE‐CXL, resulting in the biomechanical strength ...

Semiconductor Laser Digital Scanner

SPIE Proceedings, 1989
A novel semiconductor laser digital scanner composed of a monolithic semiconductor laser array and a conventional plastic lens is proposed. A high speed scanning, a simultaneous light emission, and a wide angle scanning are achieved. The semiconductor laser array consists of monolithically integrated ten index-guided 780nm emitters spaced by 0.3mm. The

Laser input scanner

Applied Optics, 1984
An input scanner based on laser technology is described that is utilized to scan cards or documents and generate digital video signals. Scanning at 18.9 lines and 18.9 pixels/mm (480 lines and pixels/in.) with a He–Ne laser, video data are generated at either 3.8 Mbit/sec (slow speed) or 11.5 Mbit/sec (high speed). Material to be scanned is placed on a
