The up-conversion (UC) and near infrared (NIR) luminescence of Er 3+ /Yb 3+ co-doped phosphate glass are investigated. In the UC emission range, the 523 nm, 546 nm green emissions and the 659 nm red emission are observed. With the increasing pump power, the intensity ratios of I 523 /I 659 , I 546 /
