Definitions
- the present invention relates to the field of luminescent materials, and more particularly to a stannate fluorescent material and a method of preparing the same. Background technique
- the Field Emission Display is a newly developed flat panel display that works like a conventional cathode ray tube and is imaged by electron beam bombardment of fluorescent material on the display. Compared to other Flat Panel Displays (FPDs), FEDs have potential advantages in terms of brightness, viewing angle, response time, operating temperature range, and energy consumption. Preparation of Good Performance One of the key factors in FED is the preparation of fluorescent materials.
- the existing cathode ray fluorescent material is mainly composed of stone A.
- the sulfur therein reacts with a trace amount of elements such as molybdenum, silicon or germanium in the cathode, it is weakened. Its electron emission results in a weaker luminescence intensity of the FED.
- a stannate fluorescent material having a molecular formula of A 2 _ x Sn0 4 :Eu x @Sn0 2 @M y ,
- A is selected from the group consisting of Ca, Sr and Ba;
- M is at least one selected from the group consisting of Ag, Au, Pt, Pd, and Cu metal nanoparticles
- y is the ratio of the moles of the elements M to Sn, 0 ⁇ y ⁇ l 10 - 2 ;
- the stannate fluorescent material has M as a core
- Sn0 2 is an intermediate layer shell
- a 2 _ x Sn0 4 :Eu x is an outer layer shell.
- a method for preparing a stannate fluorescent material comprises the following steps:
- a sol containing M selected from the group consisting of Ag, Au, Pt, Pd, and Cu metal nanoparticles At least one of them;
- the surface of the sol containing M is subjected to surface treatment, and the pH of the sol containing M is adjusted to be 10-12, and then heated and stirred at a constant temperature of 60 to 90 ° C according to the molecular formula A 2 _ x Sn0 4 :Eu x @Sn0 2 @M y
- the molar ratio of the element M to the Sn is y, sodium stannate, potassium stannate or tin tetrachloride is added, and the reaction is stirred and separated to obtain a Sn0 2 @M powder coated with M, wherein, 0 ⁇ ylx l0- 2 ;
- the mixture is subjected to heat treatment, cooling, and grinding to obtain a stannate fluorescent material having a molecular formula of A 2 _ x Sn0 4 :Eu x @Sn0 2 @M y ;
- A is selected from one of Ca, Sr and Ba elements, 0 ⁇ x 0.05, the stannate fluorescent material has M as a core, Sn0 2 is an intermediate layer shell, and A 2 _ x Sn0 4 :Eu x is Outer shell.
- the step of preparing the sol containing M is:
- a salt solution containing at least one of Ag, Au, Pt, Pd, and Cu is mixed with an auxiliary agent and a reducing agent, and reacted for 10-45 minutes to obtain a sol containing M.
