Abstract

The invention provides Tm / Ho co-doped disulfide zirconium upconversion fluorescent powder, the chemical general formula of which is ZrS2: xTm<3+>, yHo<3+>, wherein ZrS2 is a substrate, Tm<3+> and Ho<3+> are doping ions, the value range of x is 0.002-0.06 and the value range of y is 0.002-0.04. The fluorescent powder can be excited by long-wave radiation from infrared rays to green light for blue-light short wave emission, so that the deficiencies of blue light materials in the existing luminescent materials can be overcome. The invention further provides a preparation method of the Tm / Ho co-doped disulfide zirconium upconversion fluorescent powder. The method can be used for preparing the Tm / Ho co-doped disulfide zirconium upconversion fluorescent powder which has the advantages of less surface defects, good degree of crystallinity and relatively intact crystal structure. In addition, the invention further provides an application of the Tm / Ho co-doped disulfide zirconium upconversion fluorescent powder in preparation of organic electroluminescence devices.

Description

Technical field

[0001] The invention relates to the field of phosphors, in particular to a thulium-holmium co-doped zirconium disulfide up-conversion phosphor, and a preparation method and application thereof. Background technique

[0002] The full name of OLED is Organic Light Emitting Diode, or organic light emitting diode. It has many advantages, such as simple component structure, low production cost, self-luminous characteristics, short reaction time of OLED, and bendable characteristics, so that its application range is extremely wide. However, due to the lack of stable and efficient OLED blue light materials, the development of white light OLED devices and light source industries is greatly restricted.

[0003] Up-conversion fluorescent materials can emit visible light or 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-d...
