Multiple Color Emission of Mechanoluminescence and Photoluminescence from SrZnSO: Bi for Multimode Anticounterfeiting.

Mechanoluminescence materials that emit light under mechanical stimulation have attracted widespread attention in sensing, anticounterfeiting, and imaging applications. In this study, a series of SrBiZnSO (0.001 ≤ ≤ 0.

Efficient energy transfer from Bi to Mn in CaZnOS for WLED application.

A series of Bi and Mn co-doped CaZnOS phosphors with a tunable emission color have been synthesized by a high temperature solid-state reaction method. Their crystal structure, spectroscopic properties, energy transfer and thermal quenching have been investigated systematically. An intense blue-green emission band at 485 nm and a red emission band at 616 nm were observed at an excitation wavelength of 375 nm, owing to the P→S transition of Bi and the T(G) →A(S) transition of Mn, respectively.

Dendrite Integration Mimicked on Starch-Based Electrolyte-Gated Oxide Dendrite Transistors.
