Two-dimensional (2D) multiple-element layered transition metal chalcogenophosphates (TMCPs) have received tremendous attention due to their excellent carrier mobility, and absorption coefficient, displaying great potential for optoelectronic applications. Here, the novel high-quality manganese nickel phosphorous sulfur (Mn 0.24 Ni 0.76 PS 3 ) crystals are obtained by using chemical vapor transport (CVT) method. Further, thin flakes of Mn 0.24 Ni 0.76 PS 3 are achieved and employed to prepare photodetectors. Impressively, the prepared photodetectors exhibit excellent photo-response in visible light region, such as on/off ratio, and response time, a responsivity up to 10.4 mA W −1 and a detectivity of 1.31 × 10 8 Jones, demonstrating great potential for future air-stable visible light photodetection.
