Calibration of local chemical pressure by optical probe.

ABSTRACT: Chemical stabilization of a high-pressure metastable state is a major challenge for the development of advanced materials. Although chemical pressure (P_chem) can effectively simulate the effect of physical pressure (P_phy), experimental calibration of the pressure passed to local structural motifs, denoted as local chemical pressure (P_chem-Δ) which significantly governs the function of solid materials, remains absent due to the challenge of probing techniques. Here we establish an innovative methodology to experimentally calibrate the P_chem-Δ and build a bridge between P_chem and P_phy via an optical probe strategy. Site-selective Bi³⁺-trac
