Have you tried tempering the glass?

Tempered glass can be made from annealed glass via a thermal tempering process. The glass is placed onto a roller table, taking it through a furnace that heats it well above its transition temperature of 564 °C (1,047 °F) to around 620 °C (1,148 °F). The glass is then rapidly cooled with forced air drafts while the inner portion remains free to flow for a short time.

Dear Vemuri,

Ag and Au have poor adhesion with a lot of substrates such as glass and Si wafer, some adhesive layer like Cr and Ti is helpful. The thickness of the adhesive layer can be 5-10 nm. If you cannot use metallic adhesive layer, some solution-processed SiO2 layer can also be tried using precursors such as TEOS and TMOS.

Thanks a lot.

Dear Vemuri, which deposition technique did you apply? Evaporated (either thermal or e-beam) adhere only very poorly to glass (or Si or quartz ...) - sputtering may help. I made quite good experience with DC-sputtered or magnetron sputtered silver and gold layers on glass. All the best, Dirk
