Abstract

The invention relates to various antimonate luminescent materials which can convert ultraviolet light, near ultraviolet light or blue light of a luminescent element into high-strength visible light and can be used in a white light LED, and a method for preparing the same. The series of the luminescent materials comprise an undoped quaternionic antimonate material, a transition metal doped antimonate material, and a T1 like ion doped antimonate material with an S2 configuration, wherein a rare earth element doped antimonate material and the T1 like ion are similar to a rare earth ion codoped antimonate material. The luminescent materials can be used in the white light LED and relevant display and illuminating devices. The luminescent material has the advantages of unique design, cheap and easily obtained raw materials, simple preparation process, and stable chemical properties of the raw materials and excellent luminescent performance, thus the antimonate luminescent materials are ideal fluorescent powder candidate materials for the white light LED.

Description

technical field

[0001] The invention relates to a variety of antimonate fluorescent powder materials that can be used in white light LEDs (light emitting diodes) and a preparation method thereof. Said material is an electro-optical lighting material, which belongs to the field of fluorescent materials. Background technique

[0002] Solid State Lighting (Solid State Lighting, SSL) refers to a technology that uses a semiconductor light emitting diode (Light Emitting Diode, LED) to generate white light as a general lighting source. Different from vacuum tube incandescent lamps and mercury-filled fluorescent lamps, it is a brand-new lighting method with the advantages of low calorific value, low power consumption, long life, fast response, small size and flat packaging, etc. A new light source of value. It has a broad market and application prospects, and countries all over the world have formulated development plans one after another.

[0003] At present, there are mainly tw...
