Background technology
Long-afterglow fluorescent material claims luminescent powder, light-accumulating powder, noctilucence direction board etc. again.When it was subjected to rayed, part irradiates light energy was absorbed, stores; After illumination stops.To discharge luminous energy gradually.It is widely used in the warning at night sign, the emergent direction board in steamer and public place etc.After-glow brightness and after time are the most important parameters of long-afterglow fluorescent material.At present to ununified, the reliable method of the measurement of these parameters.Existing method is: earlier with long-afterglow fluorescent material after irradiation a period of time under sunshine, daylight lamp or a certain particular lamp, in the darkroom, measure the after-glow brightness of this fluorescent material with nitometer, constantly read the reading value on each moment nitometer, obtain after-glow brightness and concern over time.In all these methods, it all is separate operation that excite and the after-glow brightness of sample are measured, and uses trouble, and consistance is poor.
Summary of the invention
Purpose of the present invention aims to provide a kind of set exposure and measures in one phosphorescence afterglow measuring equipment easy to use.
Phosphorescence afterglow measuring equipment of the present invention comprise excitation source, control sample exposure exposure-control device, be used to the camera bellows that exposes and measure, specimen holder is installed on camera bellows, in camera bellows, be provided with the twilight sunset detector that receives sample after-glow light signal, the output terminal of twilight sunset detector links to each other with measurement instrument, it is characterized in that said exposure-control device is the controller that the control excitation source is lighted or closed, or be installed in the optical gate between excitation source and the specimen holder.
During work, under the control of exposure-control device, sample is subjected to the excitation source radiation exposure, end exposure, it is twilight sunset that sample will constantly discharge fluorescence, receive twilight sunset by the twilight sunset detector, and the after-glow light conversion of signals become electric signal input measurement instrument, instrument show after-glow brightness and after time parameter value.
Phosphorescence afterglow measuring equipment compact conformation of the present invention, simple, it utilize exposure-control device and disjunctor exposure, measure camera bellows, with the exposure of sample with measure and organically combine, measurement data accurately, high conformity, easy to use.
Description of drawings
Fig. 1 is that the present invention constitutes synoptic diagram;
Fig. 2 is a kind of concrete structure synoptic diagram of the present invention.
Embodiment
With reference to Fig. 1, phosphorescence afterglow measuring equipment of the present invention comprises excitation source 1, be used to the camera bellows 3 that exposes and measure, specimen holder 6 is installed on camera bellows 3, be provided with the twilight sunset detector 4 that receives sample after-glow light signal in the camera bellows, twilight sunset detector 4 links to each other with measurement instrument 5, on excitation light path, be provided with exposure-control device 2, be used to control the exciting light that shines sample surfaces.The twilight sunset that sample discharges is received by twilight sunset detector 4, and becomes electric signal to be defeated by measurement instrument 5 the after-glow light conversion of signals.Excitation source 1 can be used mercury lamp, xenon lamp, fluorescent light or metal-halide lamp.Exposure-control device can be the controller that the control excitation source is lighted or closed, and as relay, perhaps also can be mounted in the optical gate between excitation source 1 and the specimen holder 6.
Fig. 2 is an instantiation of the present invention, it comprises the excitation source 1 that is installed in the light-source box, be used to the camera bellows 3 that exposes and measure, this example, camera bellows 3 has exposure box 3a and measure case 3b two parts, utilize for these two the casees twilight sunset unthreaded hole 11 to be connected, specimen holder 6 is installed, in measure case 3b, be provided with twilight sunset detector 4 at exposure box 3a.Legend, specimen holder 6 usefulness spring carriers 14 support, and are close on the test port of exposure box bottom.The temperature control element 15 of control sample temperature is housed, as thermoelectric cooling module or heating wire on specimen holder.
For making excitation source luminous stable, usually, two electrodes of the mercury lamp, xenon lamp, fluorescent light or the metal-halide lamp that adopt are vertically installed, utilized the light turning mirror 8 that is located in the camera bellows that exciting light is refracted on the specimen holder 6 again, the light turning mirror can be plane mirror or refractive prism.In the illustrated example, exposure-control device 2 be provided in a side of in the camera bellows can around axle 9 rotate 90 ° be used to control the electronic optical gate that excites unthreaded hole 10 and twilight sunset unthreaded hole 11 to open or close, during exposure, optical gate is opened and is excited unthreaded hole 10, it closes twilight sunset unthreaded hole 11 simultaneously, when measuring twilight sunset, optical gate is closed and is excited unthreaded hole 10, and it opens twilight sunset unthreaded hole 11 simultaneously.Twilight sunset enters measure case 3b from the twilight sunset unthreaded hole, becomes electric signal to be defeated by measurement instrument 5 the after-glow light conversion of signals by twilight sunset detector 4.Twilight sunset detector 4 available silicon photodiodes or highly sensitive photomultiplier.
For making the light that shines specimen holder even, can to the light path of camera bellows 3, light diffusing board 7 be set at excitation source 1 as shown in the figure, this light diffusing board can adopt diffuse transmission plate or diffuse reflector.In this example, also installed on the excitation light path in camera bellows be used to control shine the sample light intensity excite the illumination monitoring device, it is made up of part reflective mirror 12 and photodetector 13, part reflective mirror 12 can adopt semi-transparent/catoptron, by it part exciting light is reflexed to photodetector 13, photodetector converts light signal to electric signal and is input to measurement instrument 5, shows light intensity at measurement instrument, so that regulate the light intensity of excitation source in view of the above.Measurement instrument 5 has a serial line interface with employing instrument is for well, PR-305 type instrument as available band RS-232C serial line interface, it is linked to each other with computing machine 16, utilize the twilight sunset signal of each moment fluorescent samples of computer acquisition like this, can obtain the brightness curve of twilight sunset.
