Technical field
The present invention relates to transparent glass ceramics synthesis technical field, particularly relate to a kind of novel double frequency and turn optical property and relevant transparent glass ceramics field.
Background technology
Sun power is as renewable energy source, inexhaustible.In the solar spectrum of ground, the solar radiation energy of about 99% is distributed in 220 ~ 2500 nanometer broadband wave bands, wherein visible ray (400 ~ 700nm) accounts for 71% of sunlight total radiation, and infrared light (700 ~ 2500nm) accounts for 22% of total radiation.But present various photoelectric devices all can only realize absorption and the conversion of greater efficiency to the light of respective specific spectral range.The characteristic of this selective use luminous energy of photoelectric device, has had a strong impact on the abundant absorption to sunlight and utilization.
It is reported, frequency inverted illumination mode is divided into conversion and lower conversion two kinds (F.Auzel, Chem.Rev., 2004,104,139).Upper transformation energy is converted to visible ray infrared light; Lower transformation energy is converted to visible ray UV-light.Till now, also do not have a kind of material can turn light mode these two kinds and combine, have no idea to change to visible ray while of realizing infrared light and UV-light yet.
Summary of the invention
Goal of the invention: the solution upper conversion of infrared light and the lower conversion two kinds of UV-light turn combining of light mode, and realize transparent glass ceramics of this combination and preparation method thereof.
Technical scheme: the technical problem that the present invention solves be disclose a kind of can the preparation method of transparent glass ceramics of simultaneously stability and conversion UV-light and infrared light double frequency light.
