Piezophotonics is based on a two-way coupling effect between piezoelectricity and photoexcitation properties [1,2]. The utilization of a broad range of luminescent ions, including lanthanide and transition metals can be considered for a wide variety of applications. In our works, various heterostructures and composite materials have been prepared, which can sense or harvest broad mechanical energy, including stretch, vibration pressure, handwriting and mechanical friction [4-6]. Moreover, magnetic-induced luminescence (MIL) has firstly been realized by coupling magnetic field to piezophotonics [7,8]. In real world, magnetic fields exist in many systems, and therefore the detection of magnetic field is essential for environmental surveillance, mineral exploring, and safety monitoring. For example, the large magnetic flux generated from a grid-connected power wire can be used to monitor power consumption of electric appliances in power industry. Differing from conventional magnetic sensors, the MIL-based devices enjoy competitive advantages, including environmental energy harvesting, real-time visualization, remote sensing without making electric contact, nondestructive and noninvasive detection. On the other hand, the ultimate goal of making atomically thin electronic and optoelectronic devices greatly stimulates the research two-dimensional (2D) materials [9-11], such as transition metal dichalcogenides (TMDs). Luminescent ion doped TMDs, such as MoS2 samples are firstly achieved in my group [12,13], and their structural and optical properties are investigated. The study opens the possibility for realizing novel 2D luminescent device. Through these works, great potential application can be perceived, which may contribute to future ambient energy harvesting, sensor as well as self-powered electronics and optoelectronics. The research was supported by the grant Research Grants Council of Hong Kong (GRF No. PolyU 153033/17P).
