| titleOfInvention | A kind of photochromic adjustable fluorescent material and preparation method thereof |
| abstract | The present invention relates to a kind of photochromic adjustable fluorescent material and preparation method thereof, the chemical expression of described fluorescent material is as follows：A 7‑x‑y B(PO 4 ) 6 ：xTb 3+ , yEu 3+ ；Wherein, A is selected from one kind in Ca, Sr or Ba, B is Zr or Ti, x span are (0~0.05), and y span is (0~0.05), the excitation band wave-length coverage of fluorescent material is 295~500nm, and its preparation method comprises the following steps：(1) weigh respectively comprising elements A, B, P, Tb and Eu starting compound so that the elements A in each starting compound：B：P：Tb：Eu mol ratio is (7 x y):1:6：x：Y, and each starting compound ground and mixed is uniform, obtain blend sample；(2) blend sample is calcined, is then down to room temperature naturally, regrind and produce purpose product fluorescent material.Compared with prior art, fluorescent material of the invention can be photochromic adjustable from green glow warm white feux rouges under the exciting of near ultraviolet/purple light, and technique is simple, and raw material is cheap and easy to get, green. |
