摘要:
A sealed, metal oxide, electrodeless discharge lamp having a high emissionntensity in the visible 400-700 nm range. Within the sealed container assembly of the lamp there is a source of metal atoms capable of forming a volatile oxide and a source of an oxygen containing gas. The lamp produces a plasma and volatilizes the metal into the plasma. Preferably the lamp is at a low pressure of about 20-40 torr and the metals are molybdenum or tungsten. Power is applied by inductively coupled electromagnetic radiation. A regenerative agent such as a halogen is added for recycling any deposited metal into the gas phase and to form a volatile compound with the source of metal atoms. The agent lowers the temperatures needed to volatilize the metal into the plasma. The lamp is operated by first providing energy at a low level to initiate the plasma and then supplying the metal atoms into the plasma.

The present invention provides a method of forming a flexible dichroic optical filter. The method comprises depositing a plurality of pairs of layers adjacent a substrate. Each of the plurality of pairs of layers includes a first layer formed of a silicon-and-carbon containing material having a first index of refraction and a second layer formed of a silicon-and-carbon containing material having a second index of refraction that is different than the first index of refraction.

A method and process for forming a barrier layer on a flexible substrate are provided. A continuous roll-to-roll method includes providing a substrate to a processing chamber using at least one roller configured to guide the substrate through the processing chamber. The process includes depositing a barrier layer adjacent the substrate by exposing at least one portion of the substrate that is within the processing chamber to plasma comprising a silicon-and-carbon containing precursor gas. Also provided is a coated flexible substrate comprising a barrier layer based on the structural unit SiC:H, or SiOC:H, or SiOCN:H. The barrier layer possesses high density and low porosity. The barrier layer exhibits low water vapor transmission rate (WVTR) in the range of 10−2-10−4 g·m−2d−1 and is appropriate for very low permeability applications.
