    quant_fluor_data_dict: dict

        Dictionary with XRF reference sample data. This dictionary is modified by the function.
        The dictionary must satisfy the '_xrf_quant_fluor_schema' schema.

    Returns
    -------

        No value is returned. Instead ``quant_fluor_data_dict`` is modified.
