Luminous long luminescence characteristics

In real life, people use luminous glow characteristic long , made ​​of weak light source, in particular the usefulness of the military sector , to put this material is coated on aviation instruments, watches and clocks , windows, various switches the machine marks, glow in the dark rock , etc., can also be used together with a variety of translucent plastic pressed into a variety of symbols, parts , supplies ( such as power switches, sockets , fishing hooks, etc. ) . These light -emitting components after irradiation , or unexpected power outages at night , after getting up and so it continues lightning light, so that people around discernible direction ,photoluminescent plastic to work and life. The ultrafine particles mixed with luminous material in textiles , the color more vivid , luminous textile children wear can reduce traffic accidents.
Luminous materials at home and abroad mainly zns ( ZnS ), srs ( strontium sulfide ) and cas ( calcium sulfide ) made ​​of glow green and yellow . But srs, cas deliquescent material , to a wide range of applications difficult. So mainly zns matrix luminous material on the market. Afterglow time , but it is only 1 to 3 hours , and the light ( such as sunlight ) , pigments in paint and black perishable moist air , so that in many applications in the field is limited. Add drill, bronze activated zns luminous afterglow although a long time , but it has an infrared quenching phenomenon, electric lights ( including more red ) radiation , the afterglow quickly extinguished.
