1/20/2004 · UV ? emitting phosphors find uses in various applications, such as photocopying, phototherapy, sun tanning, etc. The phosphor requirements for these applications vary. Simple methods for preparing different UV ? emitting phosphors are described.
UV – emitting phosphors find uses in various applications, such as photocopying, phototherapy, sun tanning, etc. The phosphor requirements for these applications vary.
A first step beyond simple fluorescence is to use phosphors that do not fluoresce under long UV but do so under short (254 nm) UV . It is also possible to provide phosphors that fluoresce one colour under long and another colour under short UV . However, recognition equipment using short UV will be more costly than long UV sources.
The present invention is a single-component, UV-emitting phosphor having a composition represented by the general formula (Y 1?x?y?z La x Gd y Ce Z )PO 4 where x has a value in a range from 0.001 to 0.98, y has a value in a range from 0 and 0.1, z has a value in a range from 0.01 and 0.2, and x+y+z phosphor when stimulated by 254 nm radiation emits in both the UVA and UVB regions.

The UV to white converters were prepared from broad band red, green and blue emitting powder phosphors with individual luminescence peaks near 610, 550 and 460 nm, respectively.
We are developing UV phosphors that are used in Mercury-free light source. We also provide support for customized products, so please contact us for samples if necessary. UV-Emitting Phosphor .
The new red? emitting phosphor shows an intense absorption at 396 nm, which matches well with commercial near? UV light? emitting diode (LED) chips, therefore, it is a good candidate of red phosphor used for near? UV white LEDs.
