Abstract
A method for increasing the electron excitation threshold of luminescent substance particles, comprising placing a thin and substantially uniform layer of said particles in heat exchange relationship with a mass of material of high thermal conductivity and emissivity having a surface area that supports said layer, area that is at least equal to the area of said layer, and periodically supply heat to said layer of particles and said material at the same time that said particles are exposed to an atmosphere of a material that reacts in vapor phase with the particles of luminescent substance, to carry out a surface chemical reaction in situ on the surfaces of the luminescent substance particles, to form a surface arrest or braking layer.
