Description
Technical field
The invention belongs to rare earth luminescent material fields, and in particular to a kind of red germanic acid magnesium barium fluorescent powder of novel display.
Background technology
Currently, realizing that the main path of white light LEDs is with blue light (440-470nm) LED chip excitated fluorescent powder complex group
At white light.There are two types of common combination sides：First, blue-light LED chip and yellow fluorescent powder combination；Secondly being blue-light LED chip
It is combined with red, green emitting phosphor.Wherein, garnet structure yellow fluorescent powder (YAG) matching blue-light LED chip because its efficiently,
It makes the advantages that simple and is widely used, but since spectrum poor continuity, red light portion lack, cause white light LED part
Colour rendering index is relatively low, colour temperature is higher, it is difficult to meet high-quality lighting demand.Therefore, on this basis by add rouge and powder or
High color rendering index (CRI) white light is obtained by the way of, green emitting phosphor excitated red using blue chip.
In recent years, as the increasingly raising of people's living standard and semiconductor illumination technique are constantly progressive, people are to strong
The concern consciousness enhancing of health and quality life, the requirement to illumination have been increasingly turned to from simple environmental protection and energy saving comfortable to health
Pursuit.Tradition is composed White LED by blue LED die and other color fluorescence bodies, and it is unbalanced that there are emission wavelengths, green
The shortcomings of coloured light excalation, the peak strength for being particularly present blue light is higher, easily causes physiology, psychology of people etc.
The problem of, it is difficult to meet the needs of people are to health.Therefore, researcher propose to be applied in combination in purple LED chip red (R),
The White LED of green (G), blue (B) fluorophor, compared with blue chip, this method purple light conversion of white light is more efficient, light
Spectral structure is balanced, and colour rendering index is relatively more preferable, but the chemistry and thermal stability etc. to fluorescent powder is put forward higher requirements, urgently
Suitable high density energy excitation to be developed, meet full spectrum high-quality illumination, suitable for purple or it is near ultraviolet excitated it is novel it is blue,
Green, red fluorescence powder.
