LaEr(MoO{sub 4}){sub 3} thin films have been grown by pulsed laser deposition. The films were characterized by x-ray diffraction, Rutherford backscattering, and fluorescence measurements. The results show that the deposited films were epitaxial with their c axis oriented along the surface normal. Films illuminated with 980 nm laser light show visible emission spectra. This visible emission arises as a result of the Er 4f-4f transitions and their lifetimes. Such so-called 'upconverting phosphors' are important to the development of new chemical and biological sensing applications.
