摘要：
We report detection of the low-field-high-field transition in KZnF3:Cr3+, induced by external pressure, through photoluminescence measurements at both room temperature and T = 90 K. Direct measurement of the lowest electronic level separation DELTA was accomplished through lower-temperature experiments. Pressure coefficients of DELTA and values of the crystal-field and covalence quenched free-ion parameters are given.
