The light-emitting materials may include phosphor materials and non-phosphor materials.

Compared to the oxide luminescent materials in the art, the said luminescent materials have higher luminescent intensity.

The light emitter (15) can be formed as an integral mixture of light-emitting materials and insulating materials or as separate layers of light-emitting and insulating materials.

Compared to the luminescent materials in the prior art, the said luminescent materials have higher luminous efficiency and more stable performance and structure.

Halosilicate luminescent materials and preparation methods thereof are provided.

Luminescent borates, luminescent materials, and articles incorporating such borates are provided herein.

Emissive materials are provided having the following structures:(1, 2, 3, 4, 5, 6) Devices incorporating the emissive materials are also provided.

The color rendering index of the luminescent materials is 85% or more, and the luminescent materials can be used in light-emitting diode (LED).

Some luminescent materials can be activated by the application of electrical current.

Red luminescent materials and preparation methods thereof, and an electric light source using the said red luminescent materials and preparation methods thereof are provided.

Luminescent materials and preparation methods thereof are provided.

Luminescent materials and methods of forming such materials are described herein.

Blue-green silicate luminescent materials are disclosed.

Glass ceramic luminescents have excellent physical and chemical stability.

The present invention is related to a method for marking of fibrous products, in particular fibrous cementitious products, using luminescent materials by introduction of said luminescent materials in the fibrous product.
