The orange red phosphor can be excited by 250 to 300nm ultraviolet light and emits high efficiency orange red light. The preparation technology is simple, mature and easy to be industrialized. Therefore, the invention is an excellent orange red component in high chromomeric phosphors.

Description

A kind of used for high color rendering property energy-saving lamp orange red fluorescent powder and preparation method thereof and purposes
Technical field
The invention belongs to rare earth luminescent material field, the high colour developing of particularly a kind of used for high color rendering property energy-saving lamp orange red fluorescent powder and preparation method thereof.The invention still further relates to the purposes of this product.
Background technology
Color developing is an important technology index of luminescent lamp, with colour rendering index Ra (0-100) expression.General incandescent light and daylight all have very high colour rendering index, and Ra reaches 100, is full spectrum at the 380-780nm visible light wave range.In the ordinary course of things, also can be with it as the relative standard to the evaluation of making comparisons of the color developing of luminescent lamp.
The research report is arranged in recent years: the people is under natural light or imitative natural lighting, and energy raising work, learning efficiency are of value to physically and mentally healthy, keep good visual effect, and therefore, the color developing of lighting source more and more is subject to people's attention.Especially some particular place, as dyeing industry, the lighting source colour temperature of the color evaluation of multicolor printing industry is the luminescent lamp of 5000K, 6500K, not only general colour rendering index Ra requires＞95, and R 9-R 14Each special colour rendering index also requires＞and 90.The lighting source in places such as beauty treatment, market, hospital requires also like this, as the luminescent lamp that uses common fluorescent material to make is difficult to reach the high-color rendering of above-mentioned requirements.
The color developing of the emmission spectrum decision luminescent lamp of luminescent lamp.And existing Y 2O 3: Eu (λ Main=611nm) rouge and powder, (CeTb) Mg Al 11O 19(λ Main=545nm) green powder, BaMgAl 10O 17: Eu (λ Main=450nm) or BaMgAl 10O 17: Eu, Mn (λ Main=450nm, 515nm) tricolor powder of blue powder composition still fails to make the compact type energy-saving lamp of Ra 〉=90 and the straight type luminescent lamp of Ra 〉=95 so far.There are some researches show: as long as in the luminescent lamp 405, the mercury radiation of 436nm do not reduce, the above ruddiness of the blue green light of wavelength 480-520nm and 620nm does not strengthen, and is difficult to realize Ra 〉=90 of compact type energy-saving lamp and Ra 〉=95 of straight type luminescent lamp.
Summary of the invention
In order to solve above-mentioned existing deficiency, the objective of the invention is: good stability, luminous intensity height are provided, and the emission main peak is at the used for high color rendering property energy-saving lamp orange red fluorescent powder of 630nm.
Another object of the present invention provides a kind of preparation method of orange red fluorescent powder.
The molecule of high-color rendering orange red fluorescent powder of the present invention is: (SrMg) 3(PO 4) 2: Sn
The preparation method of high-color rendering orange red fluorescent powder of the present invention may further comprise the steps:
(1) takes by weighing SrCO 3100g, MgO5g-8g, SnO21g-4g, (Nh 4) 2HP 480g-90g (each raw material weight ratio is: Strontium carbonate powder 50-55%, magnesium oxide 2-3.5%, stannic oxide 1-3%, DAP 40-50%) obtains mixture and mixes; (2) mixed raw material is put into aire tunnel kiln 1000-1100 degree calcination 2～4 hours, taken out and be cooled to room temperature; (3) powder with calcination pulverized 50 mesh sieves; (4) will sieve good powder and put into 10% hydrogen reducing furnace, 1100～1200 degree calcinations 2～4 hours, and take out and be cooled to room temperature, obtain work in-process, indexs such as test relative brightness, emission main peak, granularity; (5) work in-process are pulverized, scalping washing, wet screening, centrifugal, dried 100 mesh sieves, the test synthesis data obtain finished product.
The preparation of the high colour developing of the present invention orange red fluorescent powder, each raw material preferred weight ratio is a Strontium carbonate powder: magnesium oxide: stannic oxide: DAP=0.5: 0.03: 0.02: 0.45.
The invention has the advantages that: orange red fluorescent powder can send efficient blue green light efficiently by the 250-300nm ultraviolet excitation, and the emission main peak is used for high-color rendering luminescent lamp good stability, luminous intensity height at 630nm.Preparation technology is simple, be easy to industrialization, so the present invention is a good orange red toner component in the high colour developing fluorescent material.
Embodiment
Below the present invention is done a detailed description
