The invention provides a kind of electrochemiluminescence device, this device comprises wireless power transmission emitter, wireless power transmission receiving trap, diode, electrode and fills the electrochemical cell of electrochemiluminescence solution, described electrode is arranged in the electrochemical cell filling electrochemiluminescence solution, electrode is connected with wireless power transmission receiving trap, and diode is arranged between electrode and wireless power transmission receiving trap.
Preferably, described electrode is metal electrode, carbon electrode or conductive glass electrode.
Preferably, described diode by wired in series between electrode and wireless power transmission receiving trap.
Beneficial effect of the present invention
The invention provides a kind of electrochemiluminescence device, this device utilizes the rectified action of diode to avoid electrode produces alternating current, reduce the loss of reactive intermediate thus strengthen the electrochemiluminescence intensity of detection system in electric radio chemiluminescence, the present invention employs diode first in radio chemiluminescence, with existing electrochemical workstation compared with the technology of electrochemiluminescence coupling, the present invention is without the need to electrochemical workstation, equipment is simple, only need a wireless Blast Furnace Top Gas Recovery Turbine Unit (TRT), current potential is applied to electrochemiluminescsystem system by wireless generating and electromagnetic induction, the electric current that induction produces can excite the electrochemical luminescence signals of electrochemiluminescsystem system, meanwhile, introduce diode in a device, carry out rectification to induction current, add the electrochemiluminescence that system produces, improve sensitivity, this installation cost is low, simplicity of design.
Accompanying drawing explanation

Fig. 2 is the detection photo adding diode and the luminescence enhancement after not adding diode in electrochemiluminescence device.
Wherein, 1, wireless power transmission emitter, 2, wireless power transmission receiving trap, 3, diode, 4, electrode, 5 the electrochemical cell of electrochemiluminescence solution, is filled.
Embodiment
The invention provides a kind of electrochemiluminescence device, as shown in Figure 1, comprise wireless power transmission emitter 1, wireless power transmission receiving trap 2, diode 3, electrode 4 and fill the electrochemical cell 5 of electrochemiluminescence solution, described electrode 4 is arranged on and fills in the electrochemical cell 5 of electrochemiluminescence solution, electrode 4 is connected with wireless power transmission receiving trap 2, diode 3 is arranged between electrode 4 and wireless power transmission receiving trap 2, wireless power transmission emitter 1 and wireless power transmission receiving trap 2 in running order time, described electrode produces induction current and excites electrochemiluminescence.Introduce diode in the apparatus, make its electric current become direct current by rectified action, reduce the loss of reactive intermediate, improve luminescence efficiency.
Electrode 4 described in present embodiment is not particularly limited, and is preferably metal electrode, carbon electrode or conductive glass electrode.The device that described wireless power transmission receiving trap 2 and wireless power transmission emitter 1 are commonly used for this area, there is no particular/special requirement, described wireless power transmission emitter 1 comprises wireless power transmission module and conductive coil, wireless power transmission receiving trap 2 is conductive coil, described is not particularly limited the material of conductive coil, be preferably copper coil, copper coil in wireless power transmission emitter 1 produces induced field, accepted to produce induction current by the copper coil in wireless power transmission receiving trap 2 again, generate induction current by electrode 4 and excite electrochemiluminescence, diode 3 is series between wireless power transmission receiving trap 2 copper coil and electrode 4, by diode 3 rectified action, system ECL luminescence is effectively strengthened, improve detection sensitivity.
Fig. 2 is the detection photo adding diode and the luminescence enhancement after not adding diode in electrochemiluminescence device, wherein A is installation drawing, B is not for add diode detection photo, C is the detection photo adding diode, copper coil in wireless power transmission emitter 1 is superposed after placing with the copper coil in wireless power transmission receiving trap 2, when the energising of wireless power transmission emitter, induction current can be produced, electrochemiluminescence solution in the electrochemical cell 5 filling electrochemiluminescence solution described in experiment is preferably 1mM luminol, the 0.1M soda-sodium bicarbonate solution (pH=10.3) of 50mM hydrogen peroxide.As seen from Figure 2, under the condition not having diode, system luminescence cannot with the naked eye directly observe, but obviously can observe after adding diode that eight electrodes have stronger blue light, therefore, identical at solution, under "on" position, the electrochemiluminescence adding the electrochemiluminescsystem system of diode in a device will be eager to excel a lot more than the electrochemiluminescence of diode-less system.
Applied Electrochemistry light-emitting appearance also detects its luminous signal, and data are as shown in table 1, when Photomultiplier tube voltage is-800V, has the electrochemiluminescsystem system luminous intensity of diode to be about 12000 times of diode-less system.
