摘要：

Large gem quality type IIa crystal of isotopically pure C-12 diamond (364 mgm) was evaluated for applications as an anvil in ultrahigh pressure research. Raman microprobe and photoluminescence studies on C-12 diamond were compared with a typical type Ia natural diamond anvil used in high pressure research. Visible fluorescence in the isotopically pure diamond is an order of magnitude lower as compared to natural diamond and is ideal for spectroscopic studies in diamond cell devices. Low intrinsic strain, high purity and crystal perfection of C-12 diamond anvil offer better performance under extreme stresses.
