Title
(EN) DEPOSITION PARTICLES AND A METHOD AND APPARATUS FOR PRODUCING THE SAME
(FR) PARTICULES DE DÉPÔT ET PROCÉDÉ ET APPAREIL DE PRODUCTION DE CELLES-CI
Abstract
(EN) Disclosed is a method for producing deposition particles or intermediate particles, characterized in that the method comprises: forming a solution comprising a solvent and one or more deposit sources, aerosolizing the formed solution to produce an aerosol of precursor particles comprising the deposit source, conditioning the precursor particles to produce deposition particles or intermediate particles from the deposit source and collecting said particles. The particles may be collected as a deposit or precursor deposit on a substrate. The particles may include a matrix material and a dopant. The conditioning may be quenched to produce a desired substructure. The matrix material may be essentially optically clear. The substrate may comprise an optical fiber.
(FR) L'invention concerne un procédé de production de particules de dépôt ou de particules intermédiaires, caractérisé en ce que le procédé comprend les étapes consistant à : former une solution comprenant un solvant et une ou plusieurs sources de dépôt, mettre en aérosol la solution formée de sorte à produire un aérosol de particules de précurseur comprenant la source de dépôt, conditionner les particules de précurseur de sorte à produire des particules de dépôt ou des particules intermédiaires à partir de la source de dépôt et collecter lesdites particules. Les particules peuvent être collectées sous la forme d'un dépôt ou d'un dépôt de précurseur sur un substrat. Les particules peuvent comprendre un matériau de matrice et un dopant. Le conditionnement peut être trempé en vue de produire une sous-structure souhaitée. Le matériau de matrice peut être essentiellement transparent optiquement. Le substrat peut comprendre une fibre optique.
