There is a considerable need for optical fibre amplifiers for the wavelength range around 1300 nm for information transmission. The basic material for the amplifier light guide (10) needed therefor is to be silicon dioxide. The doping agents neodym and praseodym normally used for the desired wavelength range are, however, not suitable as they stand to obtain the required amplification. According to the invention, neodym or praseodym is used in combination with fluorine, preferably as the compound NdF3 or PrF3. In a preferred production process, an easily evaporable complex is formed from NdP3 and a further compound, e.g. AIF3, and taken in vapour form to a substrate for a deposition from the vapour phase.
