A CuInS2@ZnS nanomaterial synthesized with thiosalicylic acid and sodium citrate as dual-stabilizers is taken as a chemiluminescent luminophore, and Tris buffer containing both N2H4.H2O and H2O2 is taken as the triggering solution; introducing the H2O2 into the triggering solution can bring out greatly enhanced CL emission and obviously shortened CL process, enable the CuInS2@ZnS nanomaterial with strong flash-type and near-infrared CL; the luminophore of CuInS2@ZnS nanomaterial is synthesized by a one-pot method; compared with acridinium ester (a classical flash-type chemiluminescent substance), the CuInS2@ZnS nanomaterial is simple in synthesis method, mild in conditions and short in the required time, the synthesized CuInS2@ZnS nanomaterial is not easy to decompose under light, and the CL waveband is in the near-infrared region.
A flash-type chemiluminescence (CL) liquid composition based on a CuInS2/ZnS nanomaterial, wherein a CuInS2/ZnS nanomaterial as a chemiluminescent luminophore and a Tris buffer solution containing hydrazine hydrate and H2O2 as the triggering solution form the flash-type CL liquid composition, wherein a concentration of the hydrazine hydrate in the triggering solution is 5-30 mmol/L, wherein a concentration of the H2O2 in the triggering solution is above 0.01 mol/L, wherein a pH value of the triggering solution is 6-9.
