Zr<inf>0.05</inf>Ti<inf>0.95</inf>O<inf>2</inf>solid solution nanowires were synthesized directly on a SnO<inf>2</inf>:F-coated glass via a low-temperature hydrothermal method, and a high-sensitivity self-powered ultraviolet detector based on SnO<inf>2</inf>:F/Zr<inf>0.05</inf>Ti<inf>0.95</inf>O<inf>2</inf>heterojunction was fabricated subsequently. Zr doping not only improves the detector's photoresponse but also adjusts the response range to the short-wavelength direction. At 0 V bias, a highly responsivity of 1.03 A/W and an internal gain of 3.6 were obtained, together with favorable visible-blind characteristics and short response time. This high-sensitivity self-powered ultraviolet detector provides potential applications in wireless environmental monitoring, biological detection, and ultraviolet astronomy.
