AB Time-resolved photoluminescence spectroscopy at low temperatures is used to study the 2.3 eV emission induced by treatments causing oxygen loss in YBa_2Cu_3O_(7-x). The decay shows a biexponential behavior with components of 34 and 87 mus at 10 K. The spectroscopic data enable to separate this emission from luminescence related to specific impurity phases. The present results agree with the existence of optical transitions in the same spectral range as previously reported in literature.
