現今發光原件主要以螢光粉為發光材料,螢光粉有良好發光效率,但是螢光粉主要原料為稀土元素,稀土元素價格上卻是年年高漲。此外,在稀土元素對環境毒害的評估上,稀土元素可能對環境有重金屬毒害。發展一種無毒環保、價格便宜的發光材料並將其用在發光原件是未來重要趨勢。 本產品以無毒且具備生物可相容性之發光奈米材料取代發光原件中之螢光粉,以降低對環境毒害。此外,在夜間仍可使葉片行光合作用,將空氣中的二氧化碳固化,可達環保減碳的功能。在價格上,雖然原料成本並不便宜,但是由於使用量上非常微量,故在製程的原料成本並不昂貴。在未來的前景上,能將路樹樹葉轉換成樹燈,並且將都市夜間二氧化碳濃度降低,為一個環保減碳的照明設備。 Phosphor powder is the main material in light-emission device recently, because the light emission efficiency of phosphor powder is good (60~70%). Phosphor powder is synthesized by rare earth elements. The price of rare earth elements are expensive. In addition, rare earth element is a kind of toxic material. We replace the phosphor powder light emission device with the nontoxic and biocompatible luminescent nanomaterial, which is a method to reduce the impact in environment. This mechanism is able to pump the process of photosynthesis to convert carbon dioxide to glucose and reduce the concentration of carbon dioxide. In price, although the material is not cheap, the use is very rare. In the future, it is able to act as tree light to luminescent the road and reduce the concentration of carbon dioxide in urban.
