Tittle:
Nanosized protective coatings for oxide phosphor materials
Summary:
A Russian R&D Institute from Saint Petersburg developed a high-production technology for applying protective nanosized oxide coatings on surfaces of crystal phosphors of different chemical compositions. The Institute seeks R&D and industrial partners for technical cooperation.
Description:
Today, the most widely used luminescent lamps are mercury lamps; their quality and guaranteed service life are determined by the long-term stability of their characteristics. Deterioration of brightness and color characteristics of mercury luminescent lamps is caused by irreversible mercury adsorption on the luminophor surface and internal surface of the lamp bulb, as well by amorphization of luminophor surface, due to its impingement by high-energy ions from electric discharge area.

The Institute develops nano-technologies of protective oxide (Y2O3, Al2O3, B2O3, MgO) coatings for crystal phosphors used in monitors, luminescent lamps and plasma panels. These coatings enable protecting crystal phosphor surfaces against ion bombardment from gas discharge and significantly extend the lifetime of gas discharge devices. Coatings of MgO, which has a great capacity for secondary electron emission, enable, along with protective properties, reducing the voltage applied to the gas discharge device, and to improve its performance.

Different techniques are known for applying protective coatings onto the surface of crystal phosphor particles. Many widely used methods of protective coating application require a separate time-consuming stage within the technological process (for example, widely spread vacuum spraying of protective coating). At the same time, the manufacturing process of gas discharge devices themselves also includes thermal vacuum degassing.

The proposed protective coating application process allows integrate the necessary thermal treatment of the coating together with the existing manufacturing process of luminescent lamps or plasma panels, i.e. it does not require any additional stage for the coating application.

Current and Potential Domain of Application: Protective coatings for crystal phosphors are used in gas discharge devices: luminescent lamps and plasma panels.
Current and Potential Domain of Application
Protective coatings for crystal phosphors are used in gas discharge devices: luminescent lamps and plasma panels.
Advantages and Innovations:

The distinction of the offered coatings lays in a different method of applying and in chemical composition of film-forming solution. Coatings are applied in the course of luminescent lamps manufacture without introduction of additional process stage.

This protective plating technology is based on using widely available and inexpensive source materials; it ensures ecological safety and high flexibility of the technological process.
