Ionothermal Synthesis of a Stable Three-Dimensional [Cu4I4] Cluster Scintillator with Near-Unity Quantum Efficiency and Weak Thermal Quenching

A facile and environmentally friendly ionothermal synthesis was employed to prepare a highly luminescent hybrid scintillator, Cu4I4(C6H14N2)2 (1, (C6H14N2)2 = 1,4-dimethylpiperazine). 1 features a 3-D structure of (Cu4I4) cubane cluster...
