Weapon sight light emission system

1. A sighting device configured for use with a weapon, comprising:

a chamber coupled to said sighting device; and

a light-emitting element contained within said chamber;

wherein said light-emitting element comprises a phosphorescent material loaded within a curable resin to provide a phosphor-loaded resin;

wherein said phosphorescent material emits a first amount of visible light following exposure to a light source to provide a viewable aiming indicium in low light conditions;

wherein said phosphorescent material continues to emit said first amount of visible light after discontinuation of exposure to said light source to provide persistent luminescence;

wherein said phosphorescent material comprises strontium aluminate doped with europium and dysprosium; and

wherein said chamber contains only non-radioactive material.

2. The sighting device of claim 1 , wherein said resin adheres to one or more walls defining said chamber to fixedly secure said phosphor-loaded resin within said chamber.

3. The sighting device of claim 2 , wherein said resin comprises an epoxy resin.

4. The sighting device of claim 2 , wherein said strontium aluminate doped with europium and dysprosium loaded within said resin comprises SrAl 2 O 4 :Eu,Dy.

5. The sighting device of claim 4 , wherein said epoxy resin comprises poly(bisphenolA-co-epichlorohydrin).

6. The sighting device of claim 5 , wherein an amount of said SrAl 2 O 4 :Eu,Dy is in a range of between about 50% to about 80% by weight of said phosphor-loaded resin.

7. The sighting device of claim 6 , wherein an amount of said poly(bisphenolA-co-epichlorohydrin) is not greater than about 35% by weight of said phosphor-loaded resin.

8. The sighting device of claim 1 , wherein said chamber has a chamber depth which is not lesser than about 1/32 inch.

9. The sighting device of claim 8 , wherein said phosphor-loaded resin contained within said chamber has a corresponding phosphor-loaded resin depth which is not lesser than about 1/32 inch.

10. The sighting device of claim 1 , further comprising a reflective layer disposed within said chamber to enhance said persistent luminescence of said first amount of visible light.

11. The sighting device of claim 1 , further comprising a light conductive member, wherein said chamber is disposed inside of said light conductive member.

12. The sighting device of claim 11 , wherein said chamber is provided by a bore longitudinally disposed within said light conductive member.

13. The sighting device of claim 12 , wherein said chamber disposes in coaxial relation to said light conductive member.

14. The sighting device of claim 13 , wherein said chamber is concentrically disposed within said light conductive member.

15. The sighting device of claim 14 , wherein said light conductive member, said chamber, and said light-emitting element are cylindrically-shaped.
