Caption: Judd-Ofelt parameters (O l +-5%, x10-20 cm2), calculated radiative (tR +-5, ms) and experimental (t exp +-5, ms) lifetimes and quantum efficiencies (e) of the 4F9/2 level in 1.0mol% Dy3+-doped oxyfluoride glass, GC1 and GC2.

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".
