The NPL/Imperial team's key discovery was that a different type of crystal, p-terphenyl doped with pentacene, could replace ruby and replicate the same "masing" process at room temperature.
In the long term, the challenge will be to identify different materials that can mase at room temperature while consuming less power than pentacene-doped p-terphenyl.
The internal standard, 40 [micro]g of p-terphenyl, was added to samples prior to extraction or derivatization to account for slight variation in the experimental conditions.
