Antireflection Coatings And Other Multilayer Optical Coatings For Heat-Treatable Inorganic Substrates And Methods For Making Same

View page
US Patent:
6410173, Jun 25, 2002
Filed:
Nov 30, 1998
Appl. No.:
09/201599
Inventors:
Nanning J. Arfsten - Moorestown NJ
Axel Reich - Moorestown NJ
Frank Rodriguez - Maple Shade NJ
James F. Gavlas - Mercerville NJ
Assignee:
Denglas Technologies, LLC - Moorestown NJ
International Classification:
B32B 900
US Classification:
428701, 428702, 428697, 428699, 428428, 428432, 428216, 428212, 351166
Abstract:
The invention includes a bilayer antireflection coating, multilayer antireflection coatings, and a method for making a multilayer antireflective coated substrate. The bilayer and multilayer coatings include layers having metallic oxides, at least one layer in each of such coatings having as a material with an index of refraction at least about 1. 90, a layer comprising oxides of zirconium such that when subjected to heat treatments, such as tempering, the coatings substantially retain their optical properties. The coatings further include layers having materials of low index of refraction which include oxides of aluminum which provide coating stability and increased coating solution storage life. In the method, the layers are applied by successive dip coating techniques using solvent-based solutions and the resulting coatings can be used to coat large sized substrates which can be later cut, trimmed and/or otherwise shaped and later heat treated with substantial retention of optical properties.

B32B 900
US Classification:
428701, 428432, 428697, 428699, 428702, 359580, 359586, 4274432
Abstract:
The invention includes a thin film optical coating having a layer comprising sol-gel derived niobium oxide which is capable of providing an index of refraction of at least about 1. 90. The invention also includes a thin film optical coating having a layer comprising a sol-gel derived oxide system including niobium oxide and a second oxide component such as aluminum oxide and/or silicon oxide which is capable of providing an index of refraction of from about 1. 60 to about 1. 90. Also included in the present invention are processes for producing such thin film coatings. In the processes, a substrate is immersed in a mixture comprising niobium chloride and an alcohol, withdrawn from the mixture, and heat-treated. The mixture may also include aluminum precursors and/or silicon precursors. The heat-treatment may occur at various temperatures, including those under 200° C.

B32B019/00
US Classification:
428/697000, 427/164000, 427/169000
Abstract:
An antireflective multilayer coating including a thin film optical coating as well as a method for producing such a coating are provided. The thin film optical coating includes a layer of sol-gel derived cerium oxide, silicon dioxide, and at least one oxide of a transition metal selected from Group IIIB through Group VIB of the Periodic Table which is capable of providing a refractive index of at least about 1.90. The thin film may optionally include colloidal gold particles. A method is provided for producing a thin film optical coating including a layer of sol-gel derived cerium oxide, silicon dioxide, and at least one oxide of a transition metal selected from Group IIIB through Group VIB of the Periodic Table by immersing a substrate in a solution comprising cerium nitrate hexahydrate, an alcohol and a chelating agent, withdrawing the substrate from the solution and heat treating the coated substrate to form the metal oxides.

US Patent:
20040057142, Mar 25, 2004
Filed:
Jul 10, 2003
Appl. No.:
10/616663
Inventors:
Nanning Arfsten - Moorestown NJ, US
Assignee:
DENGLAS TECHNOLOGIES, L.L.C.
International Classification:
G02B005/08
G02B007/182
US Classification:
359/883000
Abstract:
Methods for producing stress-resistant, antireflective, thin film, sol-derived, optical coatings are provided. The methods comprise providing to a substrate a thin film optical coating including a layer of sol-gel derived cerium oxide and an oxide of silicon, nickel and/or a transition metal selected from Group IIIB through Group VIB of the Periodic Table which is capable of providing a refractive index of at least about 1.90. A multilayer stress-resistant coating is prepared by coating a substrate with an inner layer containing an oxide of titanium and an oxide of silicon, coating the inner layer with a middle layer containing cerium oxide and at least one metal oxide, and coating the middle layer with an outer layer containing an oxide of silicon. Further, a method is provided for producing a thin film optical coating including a layer of sol-gel derived cerium oxide, silicon dioxide, and at least one oxide of a transition metal selected from Group IIIB through Group VIB of the Periodic Table by immersing a substrate in a solution comprising cerium nitrate hexahydrate, an alcohol and a metal compound, withdrawing the substrate from the solution, and heat treating the coated substrate to form the metal oxides. The coatings may be subjected to heat treatments such as tempering or bending and are resistant to cracking and crazing, and thus may be applicable for making articles containing bent glass, such as display cases.
