Caption: The cut-off wavelength (lc ), optical band gap (Eopt ), Urbach energy (E), optical basicity (L), electronic polarizability (ao 2-), and interaction parameter (A) of 15RO-25Li2O-(60-x)B2O3-xCuO (R=Ca, Ba and x=0, 0.4, 0.8) glass system.

You are provided with a table from a material science paper. Here are JSON templates for two types of numeric cells: "Other" and "Glass_Compound_Amount":
{"value": "xx", "type": "Other"}
{"value": "xx", "type": "Glass_Compound_Amount", "constituent": "xx", "unit": "xx", "material": "xx"}

Please describe all numeric cells in the above table following the JSON templates (proceeding by row in a left-right, top-down direction). For each cell, output one JSON description per line. For any unanswerable attributes in the templates, set their value to the placeholder "xx".
