[0028] The preparation method of the above-mentioned thulium-doped halogen phosphorous tellurate glass up-conversion luminescent material comprises the following steps:

[0029] Step S11, according to aTeO 2 -bPbF 2 -cPbCl 2 -dZnF 2 -eP 2 o 5 :xTm 3+ The stoichiometric ratio of each element is weighed as TeO 2 , PbF 2 , PbCl 2 , ZnF 2 , P 2 o 5 and Tm 2 o 3 Powder, wherein a is 0.25-0.35, b is 0.2-0.3, c is 0.05-0.15, d is 0.15-0.25, e is 0.1-0.2, and x is 0.01-0.05.

[0030] In this step, the TeO 2 , PbF 2 , PbCl 2 , ZnF 2 , P 2 o 5 and Tm 2 o 3 The molar ratio of each component of the powder is (0.25-0.35): (0.2-0.3): (0.05-0.15): (0.15-0.25): (0.1-0.2) (0.01-0.05).

[0031] In this step, preferably T TeO 2 , PbF 2 , PbCl 2 , ZnF 2 , P 2 o 5 and Tm2 o 3 The molar ratio of each component of the powder is 0.3:0.25:0.1:0.2:0.13:0.02.

[0032] Step S13, mixing the powder weighed in step S11 evenly to obtain a precursor.

[0033] In this step, the p...

Embodiment 1

[0043] The powder with a purity of 99.99% was selected, and the TeO 2 , PbF 2 , PbCl 2 , ZnF 2 , P 2 o 5 and Tm 2 o 3 The molar ratio of each component of the powder is 0.3:0.25:0.1:0.2:0.13:0.02. Grind it in a corundum mortar for 40 minutes to mix it evenly, then burn it in a muffle furnace at 950°C for 3 hours, and then cool it to Insulate at 200°C for 2 hours, then cool to room temperature with the furnace and take it out to obtain a bulk material, which can be crushed to obtain a chemical formula of 0.3TeO 2 -0.25PbF 2 -0.1PbCl 2 -0.2ZnF 2 -0.13P 2 o 5 : 0.02Tm 3+ Up-converting phosphors.

Abstract

The invention relates to a thulium-doped halogen phosphorus tellurite glass up-conversion luminescent material with a chemical formula of aTeO2-bPbF2-cPbCl2-dZnF2-eP2O5:xTm<3+>, wherein a is 0.25-0.35, b is 0.2-0.3, c is 0.05-0.15, d is 0.15-0.25, e is 0.1-0.2, and x is 0.01-0.05. In the photo-luminescence spectrum of the thulium-doped halogen phosphorus tellurite glass up-conversion luminescent material, thulium-doped halogen phosphorus tellurite glass up-conversion luminescent material excitation wavelength is 796nm; in a 475nm wavelength zone, light emission peak is formed by Tm<3+> ion <1>G4 to <3>H6 transition radiation. The material can be used as a blue light emission material. The invention also provides a preparation method of the thulium-doped halogen phosphorus tellurite glass up-conversion luminescent material, and an organic light-emitting diode applying the material.

Description

technical field [0001] The invention relates to a thulium-doped halogen phosphorus tellurate glass up-conversion luminescent material, a preparation method and an organic light-emitting diode. Background technique [0002] Organic light-emitting diodes (OLEDs) have been widely used due to their simple component structure, cheap production cost, self-luminescence, short response time, and bendability. However, it is difficult to obtain stable and efficient OLED blue light materials, which greatly limits the development of white light OLED devices and light source industries. [0003] Up-conversion fluorescent materials can emit visible light and even ultraviolet light under the excitation of long-wave (such as infrared) radiation, and have broad application prospects in the fields of optical fiber communication technology, fiber amplifier, three-dimensional display, biomolecular fluorescent labeling, and infrared radiation detection. However, thulium-doped halogen phosphorou...
