真空蒸镀的非晶态ＭｏＯ３薄膜在Ｈ＋／碳酸丙烯酯溶液中进行电致变色时，其拉曼光谱发生相应变化，继续阳极退色时，其拉曼光谱又退回到初始状态，表明了薄膜的微结构在着色／退色循环中能发生可逆变化。阴极着色时，Ｍｏ－Ｏ（１）峰向左移动，Ｍｏ＝Ｏ（３）峰向右移动，而Ｍｏ－Ｏ（２）峰保持不动．根据拉曼峰位移与键强度的关系，我们还可以得出着色过程中注入的氢离子与Ｏ（１）结合在一起的结论。 The Raman spectra of vacuum-evaporated amorphous MoO3 films changed electrochromic in H + / propylene carbonate solution. The Raman spectra of the vacuum evaporated MoO3 films changed to their original state after the anodic decoloration was continued, indicating that the Microstructures can undergo reversible changes in the shading / fading cycles. At cathodolocation, the Mo-O (1) peak moves leftward, the Mo = O (3) peak moves to the right, and the Mo-O (2) peak remains stationary. According to the relationship between Raman peak shift and bond strength, we can also conclude that the hydrogen ions implanted in the coloring process are combined with O (1).
