Highly transparent conductive stoichiometric nanocrystalline stannic oxide coatings were deposited onto Corning® EAGLE XG® slim glass substrates. Including each coating, it was deposited for various concentrations in the aerosol solution with the substrate temperature maintained at 623.15 K by an ultrasonic spray pyrolysis (USP) technique. Nitrogen was employed both as the solution carrier in addition to aerosol directing gas, maintaining its flow rates at 3500.0 and 500.0 mL/min, respectively. The coatings were polycrystalline, with preferential growth along the stannic oxide (112) plane, irrespective of the molarity content in the spray solution. The coating prepared at 0.2 M, a concentration in the aerosol solution, showed an average transmission of 60% in the visible light region spectrum with a maximum conductivity of 24.86 S/cm. The coatings deposited exhibited in the general photoluminescence spectrum emission colors of green, greenish white, and bluish white calculated on the intensities of the excitonic and oxygen vacancy defect level emissions.

采用超声喷雾热解技术的透明导电氧化锡涂层:气溶胶溶液中摩尔浓度与改善电性能的相关性

高度透明的导电化学计量纳米晶氧化锡涂层沉积在 Corning ® EAGLE XG ®上纤薄的玻璃基板。包括每个涂层,它以各种浓度沉积在气溶胶溶液中,通过超声波喷雾热解 (USP) 技术将基板温度保持在 623.15 K。除了气溶胶导向气体外,氮气还用作溶液载体,分别将其流速保持在 3500.0 和 500.0 mL/min。涂层是多晶的,优先沿氧化锡 (112) 平面生长,与喷涂溶液中的摩尔浓度无关。以 0.2 M(气溶胶溶液中的浓度)制备的涂层在可见光区域光谱中的平均透射率为 60%,最大电导率为 24.86 S/cm。沉积的涂层呈现出绿色、绿白色、
