Shortwave
Our shortwave UV phosphors emit visible light when stimulated with 254nm UV light and do not emit light when stimulated with a 365nm UV light (normal blacklight). These properties are particularly important for security applications where you do not want a user to easily detect markings, need a mark difficult to duplicate and need a mark resistant to environmental degradation.

Our shortwave ultraviolet FlashUV7 light can be used with the shortwave UV phosphors. Please note that shortwave light can quickly cause damage to the human eye if you look into the light for only a few seconds. The eye can get burned but the damage won't be apparent for a few hours.
UVSW Shortwave Properties
- Fluoresce visibly under 254nm shortwave UV-C light
- Will not fluoresce under 365nm longwave UV-A light (black lights)
- Inorganic stable crystalline structure
- Average particle size 4.0 microns
- Decomposition temperature over 1700 degF
| Phosphor | Absorption Peak | Emission Peak |
| UVSWG | 254nm | 525nm |
| UVSWR | 270nm | 610nm |

Shortwave Phosphor part numbers:
UVSWG: 5 Gram UV Shortwave Green
UVSWR: 5 Gram UV Shortwave Red
UVSWB: 5 Gram UV Shortwave Blue
The shortwave phosphors are also available as a water based acrylic ink suspension with part numbers:
UVInkSWG-1: 1 Ounce Ink UV Shortwave Green
UVInkSWR-1: 1 Ounce Ink UV Shortwave Red
UVInkSWB-1: 1 Ounce Ink UV Shortwave Blue
We also have a special security ink which glows green under UV shortwave and red under UV longwave with part number:
UVInkLWRSWG-1: 1 Ounce Ink UV Longwave Red and UV Shortwave Green
Based on our UVLWR and UVSWG inorganic sunlight stable UV fluorescent phosphors Under Longwave 365nm UV light, ink glows Red. Under Shortwave 254nm UV light, ink glows Green. Water based acrylic binder to hold phosphor to a surface.
