Chinese scientists achieved reversible red-green photoluminescence switching in Mn-based metal halides by replacing free Cl⁻ with Br⁻. The responsive property stems from weakened hydrogen ...

α-FAPbI 3, a promising solar cell material with a cubic perovskite structure that is metastable at room temperature, can be stabilized by introducing a pseudo-halide ion like thiocyanate (SCN –) into ...

In their review, the team explored the role of halide ions on the structure and morphology of electrocatalysts. Then they examined the relationship between the halide ions and the valence states of ...

A milestone in graphene research: Chemists have succeeded in controlling the passage of halide ions by deliberately introducing defects into a two-layer nanographene system. Their paper shows new ...

The formula for a perovskite compound is typically expressed as ABX3. These are crystalline structures that bond two cations ("A" and "B", divalent metal ion) to an anion ("X"); the "B" atoms tend to ...

A group of researchers led by the Chung-Ang University in South Korea has designed a tin halide perovskite (Sn-HP) solar cell that utilizes an additive known as 4-Phenylthiosemicarbazide (4PTSC) to ...
