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. Novel syntheses for some borates (SrB4O7:Eu, CeMgB5O10:Gd, GdBO3:Pr, LaB3O6:Ce,Bi, LaB3O6:Gd,Bi, LaB3O6:Ce, Ba2B5O9Cl:Eu), a silicate (Ba2SiO5:Pb), phosphates (Sr2−xMgxP2O7:Eu) and a sulphate (CaSO4:Eu) are reported. Photoluminescence spectra of the phosphors so prepared are presented and discussed in the context of applications like phototherapy and photocopying lamps, photoluminescent liquid crystal displays, radiophotoluminescence, etc. (© 2004 WILEY‐VCH Verlag GmbH & Co.

The increase in photoluminescence and thermoluminescence of CaSO4: Dy TLD phosphor by co‐doping with Ce or P is described. Cerium is found to sensitize the PL but not the TL. P doping helps incorporation of Dy in higher concentration. PL increases by 150% while the increase in TL is about 50%. It is claimed that the CaSO4: P, Dy phosphor thus prepared is a suitable replacement for CaSO4: Dy currently in use in TLD and personnel monitoring.
