Description
Technical field
The present invention relates to the optical parameter measurement device of fluorescent powder for vacuum UV.
Background technology
The high-definition large-screen flat pannel display has become the focus and the trend of current information technical development, adopt high-octane vacuum ultraviolet-excited color plasma flat pannel display (being called for short PDP), become the outstanding person of giant-screen flat pannel display, the wall built-up colour TV is become a reality.One of critical material that PDP is used is a fluorescent powder, because the swift and violent projection of PDP technology, and used fluorescent powder and test anxious To be improved accordingly.
Because PDP fluorescent powder adopts the stronger excited by vacuum ultraviolet of photon energy, and used spectrum and optical parameter measuring instrument device is in ultraviolet one visible range usually, therefore, can't use.At present, can be used to measure the method for fluorescent powder for vacuum UV optical parametric, mainly contain three kinds in the document.The one, on the high energy synchronous radiation accelerator, utilize the vacuum-ultraviolet light excitated fluorescent powder of a certain node output luminous, again through the emission spectrum of spectrometer measurement fluorescent powder.This method not only needs to use synchrotron, and will add a whole set of optics extraction system, so complex structure, and is bulky, and price is extremely expensive, is difficult to obtain to use in actual production; The 2nd, can utilize the high-temperature plasma radiation source, constantly inject required inert gas and making it be in ionization under the high-temperature plasma state, and launching required vacuum-ultraviolet light, excitated fluorescent powder is luminous, again through spectrometer measurement fluorescent powder spectroscopic data.The system of this method is also huger, and needs continuous inert gas injecting and form high-temperature plasma, and many inconvenience are also arranged in actual applications; The third method is the vacuum ultraviolet continuous discharge spectrum that adopts deuterium lamp to produce, and through the vacuum ultraviolet monochromator beam split, obtains the vacuum ultraviolet spectroscopy of single wavelength, excitated fluorescent powder.Signal is very weak after the vacuum-ultraviolet light process vacuum ultraviolet monochromator beam split in the method, measures signal to noise ratio (S/N ratio) and poor stability.In addition, the measurement optical path length of this method, vacuum tightness requires high.And above-mentioned these measuring methods can only obtain the part optical parametric of vacuum uv phosphor, have many problems in actual applications.
Summary of the invention
Purpose of the present invention aims to provide a kind of optical parameter measurement device of simple in structure, price is low, volume is little, measurement parameter is complete, precision is high, easy to use fluorescent powder for vacuum UV.
The optical parameter measurement device of the fluorescent powder for vacuum UV of invention comprises the vacuum tank of being with vacuum pump, be provided with the carriage that connects with drive unit in the vacuum tank, be distributed with the sample disc that several put fluorescent powder on the carriage, stretch out the code device that the vacuum tank end is equipped with test sample dish numbering at drive unit, at least one excitation source and radiative photoelectric measuring instrument of at least one reception sample to the sample disc irradiates light is installed on vacuum tank.
Above-mentioned vacuum tank is vacuum state or is filled with inert gas, as helium, xenon, neon, nitrogen etc.
Said photoelectric measuring instrument can be device in vacuum tank and the brightness detector that is connected with measurement instrument outside the case, or be plugged on the nitometer of vacuum tank eyelet, or the spectral radiometer that links to each other with vacuum tank by condenser or optical fiber.
Said excitation source can be vacuum UV lamp or electron-beam excitation source or ion beam excitaton source or laser beam excitaton source.
Drive unit can be worm and gear transmission or gear drive, also can be that stepper motor directly drives.This drive unit driven bracket is made rotation or moving linearly.
For preventing direct reflection, usually, make the sample in the excitation source vertical irradiation sample disc, photoelectric measuring instrument receives sample emission light from the direction with sample normal angle at 45, perhaps excitation source is from shining sample with the direction at sample normal angle at 45, and photoelectric measuring instrument receives sample emission light perpendicular to the sample disc direction.
The effect that compared with the prior art the present invention obtains is: the present invention is turned round by the drive unit driven bracket; make the sample in the corresponding numbered samples dish of excitation source direct irradiation; utilize photoelectric measuring instrument; reception is in the emission light of the fluorescent powder sample of vacuum or inert gas shielding; can record the spectral distribution of vacuum uv phosphor, many optical parametrics such as relative brightness, chromaticity coordinates, excitation, colour temperature, peak emission wavelength and radiancy, bandwidth.It is simple in structure, price is low, and measurement parameter is more complete, the precision height, and signal is strong, and is easy to use.
