Compound, at high temperature 600-1300 degree, sinters 1-8 hour, is prepared as Emission in Cubic hexagonal phase mixed crystal luminescent material.Manganese, europium
There was added of ion beneficially produces orange or red luminescence, and samarium, cerium, copper, erbium there was added and beneficially produce green emitting, silver, gold, copper
There was added and beneficially produce blue-light-emitting, Emission in Cubic hexagonal phase mixed-crystal structure luminescent material is oval, be conducive to mixing with
Surface processes.
Luminescent ceramic matrix in the present invention is zinc sulfide, and doping activator is in manganese, europium, samarium, cerium, copper, silver, gold, erbium
At least one acid ion compound, such as manganese nitrate, copper chloride etc., at high temperature 600-1300 degree, sinter 1-8 hour, preparation
Become Emission in Cubic hexagonal phase mixture luminescent material.Manganese, europium ion there was added that beneficially to produce orange or red luminous, samarium, cerium,
Copper, erbium there was added and beneficially produce green emitting, and silver, gold, copper there was added and beneficially produces blue-light-emitting, Emission in Cubic hexagonal phase mix-crystal
Body structure light-emitting material is oval, is conducive to mixing to process with surface.
Elastic resin rubber in the present invention is the one in silicone rubber, silicones, and with highly sensitive compressive resilience deformation
Luminescent material is sufficiently mixed and is prepared as coating, and by printing, stand is scraped, applied, rejection film method is prepared as thin film.Liquid or colloidal silicon
Glue silicones is conducive to simple film forming, or uses mould molding, and during use, it forms colloid through being dried, and has compressive resilience.
Being also beneficial to need to adjust luminescent material additional proportion according to pressure-sensitivity in time, the best sensitivity of the thinnest elasticity is the highest, more
Thick bearing pressure is the strongest.Containing highly sensitive compressive resilience deformation luminescent material and other transparent elastic resin rubber in the present invention
Mixing can also produce luminescence, and silicone rubber, silicones are common and inexpensive material, and the superior performance such as waterproof.
