METHOD OF FORMING A LUMINESCENT LAYER ON A CARRIER AND LOW-PRESSURE MERCURY VAPOUR DISCHARGE LAMP HAVING A LAYER APPLIED TO A CARRIER BY MEANS OF SUCH A METHOD

摘要

A method of forming a luminescent layer on a glass carrier (such as the wall of a discharge vessel of a low-pressure mercury vapor discharge lamp) from a suspension of grains of a luminescent material and a quantity of binder in a suspension medium. According to the invention, the suspension medium preferably consists of water and the binder mainly comprises fibrous crystals of boehmite.
