BaO-P₂O₅ (BP) and BaO-La₂O₃-Al₂O₃-P₂O₅ (BLAP) glass thin films with a thickness of 80–160 nm, which have a high content of residual moisture and a high concentration of non-bridging oxygen (NBO) as a medium for proton movement, were fabricated through sol-gel spin coating using water as a solvent. All the fabricated glass thin films exhibited amorphous phase and glassy, defect-free surfaces. The thickness of the BP thin films decreased as the annealing temperature increased. The increase in the annealing temperature led to a decrease in NBO/BO ratio which is thought to affect proton mobility and an increase in mobile proton concentration. Therefore, it seems that high proton concentration by residual water appears to have a dominant effect on fast proton conduction. The calculated proton concentrations of the fabricated BP thin films were decreased from 55.9 mol/l to 45.5 mol/l as the annealing temperature increased from 300 °C to 400 °C. The conductivity of BP and BLAP thin films annealed at 400 °C were 2.52 × 10⁻⁶ S/cm and 1.32 × 10⁻⁵ S/cm, respectively, at 300 °C. BLAP thin film showed significantly improved conductivity compared to those of BP glass thin films due to its high proton concentration.

BaO-P ₂ O ₅（BP）和BaO-La ₂ O ₃ -Al ₂ O ₃ -P ₂ O ₅通过溶胶-凝胶旋涂法制备了厚度为80-160 nm的（BLAP）玻璃薄膜，这些薄膜具有较高的残留水分含量和高浓度的非桥连氧（NBO）作为质子运动的介质。使用水作为溶剂。所有制造的玻璃薄膜均表现出非晶相和玻璃状，无缺陷的表面。BP薄膜的厚度随着退火温度的升高而降低。退火温度的升高导致NBO / BO比的降低，这被认为会影响质子迁移率并增加可移动质子浓度。因此，似乎残留水引起的高质子浓度似乎对快速质子传导起主要作用。制成的BP薄膜的计算出的质子浓度从55.9 mol / l降低到45。当退火温度从300°C升高到400°C时为5 mol / l。在400°C退火的BP和BLAP薄膜的电导率为2.52×10 在300°C下分别为^-6  S / cm和1.32×10 ^-5 S / cm。与BL玻璃薄膜相比，BLAP薄膜由于其高质子浓度而显示出显着改善的电导率。
