The invention relates to a 1064nm
lead fluoride based up-conversion
luminescence material and a preparation method thereof, and belongs to the technical field of
luminescence materials. Present
fluoride up-conversion
luminescence materials are only responsive to 980nm light. The 1064nm
lead fluoride based up-conversion luminescence material is characterized in that the general formula of the 1064nm
lead fluoride based up-conversion luminescence material is (Pb1-xMx)F2:Er<3+>,Yb<3+>, M is one of Ca, Sr and Ba, x is not greater than 0 and is less than 1, and the 1064nm lead
fluoride based up-conversion luminescence material can be excited by 1064nm
wavelength light and can emit 551nm
wavelength light. The preparation method of the up-conversion luminescence material is a high temperature
solid phase method, reaction raw materials comprise fluorides of Yb and Er or comprise the fluorides of Yb and Er and a
fluoride of one of Ca, Sr and Ba, and also comprise a fluoride of Pb, and the preparation method comprises the following steps:
processing all the reaction raw materials to prepare a (Pb1-xMx)F2:Er<3+>,Yb<3+> precursor, wherein M is one of Ca, Sr and Ba, and x is not greater than 0 and is less than 1; carrying out
grinding mixing of the precursor and a fusing assistant NaF to obtain a
sintering material base; and putting the
sintering material base in a
crucible with the bottom spread with a layer of Na2SiF6, and carrying out a high temperature
solid phase reaction in an open space to obtain the (Pb1-xMx)F2:Er<3+>,Yb<3+> target product.
