Deep-trap ultraviolet persistent phosphor for advanced optical storage application in bright environments.

Extensive research has been conducted on visible-light and longer-wavelength infrared-light storage phosphors, which are utilized as promising rewritable memory media for optical information storage applications in dark environments. However, storage phosphors emitting in the deep ultraviolet spectral region (200-300 nm) are relatively lacking. Here, we report an appealing deep-trap ultraviolet storage phosphor, ScBO:Bi, which exhibits an ultra-narrowband light emission centered at 299 nm with a full width at half maximum (FWHM) of 0.

Ultraviolet-B and Near-Infrared Dual-Band Luminescence in Bi/Bi Codoped Persistent Phosphor for Optical Storage Application.

Discovering multifunctional luminescent materials to meet the demands of modern spectroscopy is of great significance. However, it is a standing challenge to enable multiple luminescence properties in a single material system via single metal ion doping. Here, we report the inherently Bi/Bi codoped CaGaGeO persistent phosphor where Bi is in situ reduced to Bi.

Molecular modelling and synthesis of a new collector -butyl -(1-chloroethyl)carbonodithioate for copper sulfide ore and its flotation behavior.

Based on the homology principle in advanced pharmaceutical chemistry, a new high efficiency and low toxicity collector, -butyl -(1-chloroethyl)carbonodithioate, was designed. By using molecular simulation technology, MS (Materials Studio) was used to build the molecular model of the collector. The molecular structure was relaxed and optimized.
