This disclosure relates generally to glass products having a UV protective coating. The coating is a porous, nano-structured coating having pores sized within the range of UV radiation. The porous structure may scatter UV light, protecting laminated interlayers and interior space protected by the glass products. The UV protective coating may be used in glass laminates having UV-sensitive interlayers, including switchable films where UV exposure may be limited.

An element composed of glass displaying reduced electrostatic charging is provided. The element is suitable as a housing component for electronic elements, an element implantable in the human or animal body including glass tubes for reed switches or transponders and/or implants. The glass includes at least one alkali metal and/or an alkali metal oxide and has a surface. The concentration of at least one alkali metal and/or the alkali metal oxide increases from the surface in a direction of an interior of the element in such a way that a maximum concentration of the alkali metal and/or the alkali metal oxide occurs at a distance of not more than 60 nanometres, measured perpendicularly from the surface.

Glass-based articles that include a compresive stress layer extending from a surface of the glass-based article to a depth of compression are formed by exposing glass-based substrates to water vapor containing environments. The glas-based substrates are substantially free or free of alkali metal oxides. The methods of forming the glass-based articles may include elevated pressures and/or multiple exposures to water vapor containing environments.

The present disclosure is to provide a method of producing a LTP or LATP crystal particle that has reduced impurity contamination, high crystallinity, and excellent dispersibility.

A glass substrate includes at least one selected from the group consisting of Li, Na, K, Mg, Ca, Sr, Ba and Zn as a reaction factor component, and includes a surface depletion layer at a surface side of the glass substrate. A total molar concentration (mol/cm.sup.3) of the reaction factor component in the surface depletion layer is decreased relative to an inside of the glass substrate. A total depletion amount (mol/cm.sup.2) of the reaction factor component in the surface depletion layer is 1.0010.sup.8 or more. The glass substrate has a refractive index (n.sub.d) of 1.68 or more.

Process for treatment by an ion beam of a glass material where: the acceleration voltage of the ions is between 5 kV and 1000 kV; the temperature of the glass material is less than or equal to the glass transition temperature; the dose of nitrogen (N) or oxygen (O) ions per unit of surface area is chosen within a range of between 10.sup.12 ions/cm.sup.2 and 10.sup.18 ions/cm.sup.2 so as to reduce the contact angle of a drop of water below 20; a prior pretreatment is carried out with argon (Ar), krypton (Kr) or xenon (Xe) ions in order to strengthen the durability of the superhydrophilic treatment. Superhydrophilic glass materials of long duration are thus advantageously obtained.

A method including obtaining an at least partially transparent object (1), providing a mask (6) defining at least one opening (8) wherein the contour corresponds to a profile of the anti-counterfeit marking to be structured, the mask (6) covering a surface of the at least partially transparent object (1) at the areas not to be structured, structuring the anti-counterfeit marking by bombarding the at least partially transparent object (1) by an ion beam (14) through the at least one opening (8) of the mask (6), the mechanical properties of the mask (6) being sufficient to prevent the ions of the ion beam (14) from etching the surface of the at least partially transparent object (1) at the areas where this surface is covered by the mask (6), removing the mask (6), and placing the at least partially transparent object (1) in a bath (16) at alkaline pH.
