Application

Rubidium carbonate can be used:
  • As a strong n-dopant to fabricate quantum-dot light-emitting diodes. The addition of rubidium carbonate enhances the thermal stability of Mg-doped ZnO electron transport layer.
  • As a precursor to prepare rubidium-promoted iron catalyst for Fischer–Tropsch synthesis.
  • As a strong base for the cross-coupling reaction between organobismuthines and aryl or heteroaryl halides to synthesize triarylbismuthines.
  • To prepare rubidium borosilicate glasses.
