“…[1][2][3][4][5][6] Owing to the rich electronic energy levels and long-lived excited states of rareearth (RE) ions as well as their unique photon absorption spanning (vacuum) ultraviolet (UV)/visible/infrared (IR) range, RE-based upconversion materials have been specifically designed and extensively reported for the colorful upconversion phenomena in (nano)particles, films, glasses, ceramics, hybrid matters, etc. [7][8][9][10][11] Amongst the reports, conversion of two or more near-IR (NIR) photons to one visible/far-red photon is becoming the most popular research field due to its innate advantages of efficient absorption centers (Yb 3+ , Nd 3+ , Er 3+ , etc.) and acceptors (Er 3+ , Ho 3+ , Tm 3+ , etc.…”
