Process for producing electroluminescent device

A process for producing an electroluminescent device comprising a luminescent layer located between two electrodes formed on an insulating substrate,

• wherein the luminescent layer comprises a host material to which a luminescent center element is added and the host material is composed of an alkaline earth metal element selected from the group consisting of Be, Mg, Ca, Sr, Ba and Ra, and a second element selected from the are consisting of O, S, Se, Te and Po,
• which process comprises forming the host material by chemical vapor deposition to react a first gas of an organic compound containing the alkaline earth metal element and a second gas of a compound containing the second element in a reactor,
• the first gas being formed from a cyclopentadienyl compound selected from the group consisting of bis-pentamethylcyclopentadienyl strontium-THF adduct, bis-pentamethylcyclopentadienyl calcium-THF adduct and bis-pentamethylcyclopentadienyl barium-THF adduct.

• reacting at bird gas of a compound containing the luminescent center element, composed of tridipivaloylmethanized cerium, with the first gas and the second gas in the reactor, thereby doping the host material with the luminescent center element.
