Interfacial charge transfer triggering broadband infrared emissivity in Y2O3/rGO composite

Key Points

• Broadband infrared emissivity significantly improved in Y2O3/rGO composite materials.
• The measure of infrared emissivity increased by more than 30% in comparison to pure Y2O3.
• Experimental analysis focused on the interactions between interfacial charge transfer and emissivity.
• This highlights the potential of using Y2O3/rGO composites for effective thermal management solutions.
