· Pr1 Bi2 Br1 O4

Pr₁Bi₂Br₁O₄ is an experimental mixed-halide oxide semiconductor combining praseodymium, bismuth, bromine, and oxygen—a composition that falls within the emerging class of halide perovskites and related layered oxide structures. This material is primarily of research interest for optoelectronic and photonic applications, where the combination of heavy elements (Bi, Pr) and halide chemistry offers potential for tunable bandgaps, luminescence, or photocatalytic activity. While not yet established in high-volume industrial production, compounds in this family are being investigated as alternatives to conventional semiconductors for next-generation devices where conventional materials face limitations in performance or environmental compatibility.

Export Control

RoHS, REACH, and Prop 65 statuses are validated against official substance lists (ECHA SVHC Candidate List, OEHHA Prop 65, RoHS Annex II). Other regulations are estimated from composition and material classification. All screening is a starting point for due diligence — always verify with your supplier before making compliance decisions.
