WebThe carbon-filament bulb was actually highly inefficient, but it banished the soot and fire hazards of coal-gas jets and thus soon gained wide acceptance. Indeed, thanks to the incandescent lamp, electric lighting became an accepted part of urban life by 1900. The carbon-filament bulb was eventually… Read More use in lighting systems WebEu 3+ /Tb 3+ co-doped luminescent glasses are well-known to emit intense yellowish-orange light resulting from the energy transfer from green-emitting sensitizer Tb 3+ ions to red-emitting activator Eu 3+ ions. Obtaining highly efficient blue light from lanthanide ions remains a challenge due to their weak down-converted emission.
