· Ba2DyGaSe5

Ba2DyGaSe5 is a quaternary chalcogenide semiconductor compound combining barium, dysprosium, gallium, and selenium—a research-phase material explored for its potential optoelectronic and photonic properties. This material belongs to the family of rare-earth-containing selenides, which are investigated for infrared transmission, nonlinear optical effects, and wide-bandgap semiconductor applications where conventional materials fall short. While not yet widely deployed in production, compounds in this class are of interest to researchers developing next-generation infrared optics, deep-UV detectors, and specialty photonic devices where rare-earth doping provides tunable electronic properties.

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.
