The present invention relates to a kind of preparation and application of the solid phosphor probe material based on Mn doping ZnS quantum points, it is therefore an objective to solves existing phenol compound detection method complex operation, cost height, the technical problem of poor selectivity.The technical scheme is that：First using Mn as dopant, Mn doping ZnS quantum points are prepared by hydrothermal synthesis method, then the quantum dot and tyrosinase are fixed on aerosil, the solid phosphor probe material based on Mn doping ZnS quantum points is made.Detection available for phenol compounds such as catechol, phenol, nitrophenols, and in measure without complicated sample pretreatment process, the generation of room temperature phosphorimetry is also without addition oxygen scavenger and derivant, and the interference of the scattering light such as autofluorescence and Raman, Rayleigh of sample can be avoided, greatly improve sensitivity and the selectivity of detection, solid probe material easily separates with solution to be measured simultaneously, replys room temperature phosphorimetry performance, therefore can realize the recovery and recycling of phosphorescence probe. |
