- Tungsten bronze, specifically a type called NaWO, is developed as a more durable, near-infrared (NIR) shielding material for energy-efficient smart windows, which typically fail due to film adhesion issues.
- Researchers successfully integrated NaWO into a glass matrix during the glass-making process, using specific additives (HWO and SbO) to enhance its properties and ensure effective NIR shielding.
- The optimized glass composition showed impressive NIR-shielding (62.8% efficiency) and visible light transmittance (67.7%), making it a competitive alternative to traditional glass options under sunlight.
