ELECTROLUMINOFOROS DE SULFURETOS DE ZINCO E PROCESSO PARA O SEU FABRICO |
摘要 |
Zinc sulfide electroluminophores are prepared from solutions of zinc salts with hydrogen sulfide. The zinc sulfide compounds are mixed with activator and coactivator compounds to produce luminophores, and the mixtures are fired in the presence of fixing agents. These fired materials are then treated in an acid bath, washed, neutralized, and optionally filtered and dried. |
