摘要

Cr and Nd co-doped glasses are potential gain media for solar pumped lasers (SPLs). Tanabe-Sugano analysis shows that Cr doped Si-B-Na-Al-Ca-Zr-O (SBNACZ) glass contains a mixture of Cr3+ with octahedral coordination and Cr6+ with unknown coordination. The crystal field parameters for Cr3+ were Dq = 1574 cm(-1), B = 792.2 cm(-1), C = 3005 cm(-1) and Dq/B = 1.99, indicating a low covalency of Cr-O bonds. We compared the quantum efficiency (QE) of Nd and Cr co-doped SBNACZ glass with Nd doped SBNACZ glass to determine the Cr3+-> Nd3+ transfer QE. The Cr2O3 content was fixed at 0.1 mol.% and the Nd2O3 content was varied between 0.1 and 1 mol.%. A maximum transfer QE of 20% was obtained at 0.5 mol.% Nd2O3. Cr3+-> Nd3+ energy transfer is dominated by the coulombic interaction mechanism. The clustering of Nd3+ was a limiting factor for increasing the transfer QE with higher Nd3+ concentrations.
