Summary form only given. Er/sup 3+/ has been shown to be a good rare-earth dopant of crystals and glasses for practical applications as laser-active media and infrared-to-visible signal converters. In the present work we used low-temperature photoluminescence measurements in the 4 to 300 K range to study the effects of temperature on some radiative transitions of Er/sup 3+/ in lead-tellurium-germanate glass being developed for fiber laser applications. The transitions studied include the green emission lines /sup 4/S/sub 5/2//spl rarr//sup 4/I/sub 15/2/ (550 nm) and /sup 2/H/sub 11/2//spl rarr//sup 4/I/sub 15/2/ (530 nm), the red emission band /sup 4/F/sub 9/2//spl rarr//sup 4/I/sub 15/2/ (670 nm), and the near-infrared band /sup 4//sub 3/2//spl rarr//sup 4/I/sub 15/2/ (850 nm).
