In this article, we show that the surface resistance of transparent SrTiO3 material could be reduced largely under irradiation from various light sources, especially the deuterium lamp and UV LED. The intrinsic response times, when the light is on and off, can be different by around 1 order of magnitude but this difference can be adjusted externally. We also show that the resistance change can also largely depend on the sunlight intensity. These results show the promise of the light-sensing application of this transparent SrTiO3 material.
