A hermetically sealed glass package and method for manufacturing the hermetically sealed glass package are described herein using an OLED display as an example. Basically, the hermetically sealed OLED display is manufactured by providing a first substrate plate and a second substrate plate and depositing a frit onto the second substrate plate. OLEDs are deposited on the first substrate plate. An irradiation source (e.g., laser, infrared light) is then used to heat the frit which melts and forms a hermetic seal that connects the first substrate plate to the second substrate plate and also protects the OLEDs. The frit is glass that was doped with at least one transition metal and possibly a CTE lowering filler such that when the irradiation source heats the frit, it softens and forms a bond. This enables the frit to melt and form the hermetic seal while avoiding thermal damage to the OLEDs.

Silicate glasses have no long range order and a short range order similar to their crystalline counter-parts. Therefore, their key structurally distinct information lies in the medium range. The statistics of rings, describing the 3D connection of tetrahedral units, is a crucial indicator of the medium range structure. However, no experimental techniques have succeeded in quantifying the ring statistics. Here we show a heuristic method to extract ring structure information from the first sharp diffraction peak (FSDP) of the neutron scattering structure factor. We demonstrate that, for 81 commercially important silicate glasses, the real space representation I(r)-s of their FSDPs, can be consistently represented by a sum of three compressed exponentially decaying sine functions with three fixed periodicities. We propose these three characteristic periodicities are commensurate with the statistically averaged sizes of ≤4-, 5- and ≥6-membered rings, with their relative amplitudes reflecting the relative fractions. Our results are validated using Molecular Dynamics simulated glass structures. The derived ring structure information provides an insight into the structural origin of the anomaly in hardness of aluminosilicate glasses.

The disclosure is directed to glass frits materials containing phosphors that can be used in LED lighting devices and for methods associated therewith for making the phosphor containing frit materials. Suitable non-lead glasses have a composition, in mol%, in the range of 20-24% K20, 8-12% ZnO, 2-6% A1203, 35-41% 3203 and 22-28 Si02. Suitable leaded glasses have a composition, in mol%, in range of 72-79% PbO, 8-13% A1203, 8-13% B203, 2-5% Si02 and 0-0.3% Sb203. Commercial high-lead glass can be used in practicing the disclosure. Among the unique advantages are the ability to blend two or more phosphors within the same frit layer which will yield a multi -phosphor- containing glass after firing; the ability to deposit the phosphor onto a substrate into a desired geometric pattern; and the fluorescing layer can be applied to the active plane, with the glass serving as protective substrate.
