光致变色材料已被广泛研究，因为它们在许多应用中具有很大的吸引力和前景。氧化钨（WO ₃）是一种典型的光致变色材料，已经引起了广泛的关注。迄今为止，在WO ₃光致变色的不同子领域中已经取得了许多进展，主要集中在增强WO ₃光致变色特性上，这不仅取决于化学特征，还取决于微观结构，界面和杂化组分。这篇综述旨在总结改进WO _3的不同高级策略的最新进展。光致变色特性，例如快速的光响应（在1分钟内），强而稳定的光致变色，可见光着色和可逆的光致变色。然而，对于大规模商业应用而言，实现这些性能仍然是挑战。另外，尽管已经制造了一些基于光致变色的基于WO ₃的装置，但是许多先前的研究仅限于实验室研究目的。为了清楚地解决上述问题，本文将对以下方面进行讨论。首先，描述WO ₃的基本光致变色。其次，将总结改善光致变色性能的各种进展。第三，WO ₃的光学应用基光致变色材料将进行审查和讨论。最后，提出了基于WO ₃的光致变色材料和器件的发展趋势的观点。

Advances on tungsten oxide based photochromic materials: strategies to improve their photochromic properties

Photochromic materials have been extensively studied because they are quite attractive and promising for many applications. Tungsten oxide (WO₃), a typical photochromic material, has attracted considerable attention. So far, many advances have been achieved in different subfields of WO₃ photochromism, mainly focused on the enhancement of WO₃ photochromic properties, which depends not only on the chemical features but also on the microstructures, interface and hybrid components. This review aims to summarize recent progress in different advanced strategies to improve WO₃ photochromic properties, such as a fast photoresponse (within 1 min), strong and stable photochromism, visible-light coloration and reversible photochromism. However, it is still challenging to achieve these properties for large-scale commercial applications. In addition, many previous studies have been limited to lab research purposes, although some photochromic WO₃-based devices have been fabricated. To address the above-mentioned issues clearly, this review will provide a discussion of the following aspects. First, the fundamental photochromism of WO₃ is described. Secondly, various advances towards improving its photochromic properties will be summarized. Thirdly, the optical applications of WO₃-based photochromic materials will be reviewed and discussed. And finally, a perspective on the development trends in WO₃-based photochromic materials and devices is proposed.
