用简便的水热法制备了大规模、高纯度、均匀的一维Ag2MO4 （M = Cr、Mo、W）。制备的Ag2MO4材料具有线性电流-电压（I-V）特性和良好的光响应。随着光源的开关，在0.1 V的电压下，电流可以在高低值之间可逆切换。因此，结果表明，这些化合物的光-暗电导率与金属的离子电势有关。对硅酸银和钒酸银的光响应的扩展也显示出类似的令人兴奋的结果，表明它们在未来光开关器件中的潜在应用。
Large-scale, high-purity, and uniform one-dimensional Ag2MO4 (M = Cr, Mo, and W) were obtained by a facile hydrothermal method. The as-prepared Ag2MO4 materials exhibited linear current-voltage (I-V) characteristics and excellent photoresponse. As the light source was switched on and off, the currents could be reversibly switched between high and low value at the voltage of 0.1 V. Thus, the results suggested that the light- to dark-conductivity ratios of these compounds were correlated with the ionic potential of the metal. The extension of the photoresponses to silver silicate and silver vanadate also showed similar exciting results, indicating their potential applications in photoswitch devices in the future.
