In addition, the fluorescent powder disclosed by the invention can be used for carrying out structure fine adjustment by partially replacing Al/F elements with Si/O, and changing the existence proportion of different valences of lanthanide series metal in the fluorescent powder, so as to regulate and control the light emission property of the fluorescent powder.
Description
Technical field
The present invention relates to a kind of phosphor material powder, particularly a kind of improve its optical property partly replace the aluminate class compound fluorescent material of Al/F element with the Si/O element.
Background technology
Along with the evolution of civilization and the enhancing of carbon reduction environmental consciousness, various countries are just step by step with photodiode (Light Emitting Diode at present, LED) replace conventional light source, to have a volume little because of photodiode, current consumption is low (to be 1/10th of white flag bulb, fluorescent lamp 1/2nd), life-span is long, luminous efficiency is good, the advantages such as operant response speed is fast, can solve the problem that conventional light source is difficult to overcome, therefore be applied at present red signal lamp used by rail workers, automotive luminaire, the assemblies such as indicating meter, because it meets the environmental protection concept of emphasizing now, is described as 21st century it " green illumination light source ".
Japan day inferior (Nichia) chemical company proposed to excite by blue-ray LED yttrium aluminum garnet (the Cerium-doped yttrium aluminum garnet of cerium doping in 1996; YAG:Ce) fluorescent material produces yellow fluorescence, its with blue light after can produce cold white light, this is first white light-emitting diodes, however because this white light lacks ruddiness composition, therefore its color rendering is low, and this patent by day an inferior patent limited.Because the full spectral band of white light-emitting diodes palpus tool is given out light and just can be reached high color rendering and desired color temperature, except blue light diode collocation YAG and red fluorescence powder, also have that blue light diode collocation is green, red fluorescence powder and UV-LED arrange in pairs or groups bluish-green red trichromatism fluorescent material etc. blendes together the white light mode, if wherein will produce desirable colour temperature (warm white), UV-LED collocation three-color phosphor has the better efficient of giving out light, and is present primary research topic therefore exploitation is fit to blueness, green, the red fluorescence powder of ultraviolet excitation.
The research that fluorescent material is relevant at present is except the exploitation of new host lattice, other element that mixes in host lattice replaces host lattice element originally and uses and improve luminous and also be common research direction, such as the people such as Duan in 2011 on Chemistry of material periodical (Chemistry Materials, dx.doi.org/10.1021/cm103495j) deliver Re

Summary of the invention
Purpose of the present invention aims to provide a kind of fluorescent material that has more stability.
An of the present invention purpose aims to provide a kind of fluorescent material of promoting color rendering.
Another object of the present invention aims to provide a kind of making method of simplification and the cost that reduces fluorescent material.
